The Smraza 104pcs Kit offers a more focused value choice, while the Electronics Component Fun Kit is better for beginners who need an e-book, breadboard, and basic components before soldering. The main choice is between a guided electronics set and a perfboard-heavy bundle designed for builders who already understand circuit layouts. Buyers also need to weigh useful connector variety against inflated piece counts filled with parts they may rarely touch. Continue reading for my full ranking logic, buying factors, and buyer-specific recommendations.
Complete the kit
Key Takeaways
- The 174-piece kit earns the top position because it balances double-sided boards and headers more convincingly than the bulk-focused 365-piece bundle.
- The Electronics Component Fun Kit is the clear beginner pick: none of the other listed sets combines an e-book, breadboard, jumper wires, components, and soldering supplies in the same package.
- Smraza’s 104-piece set occupies the value sweet spot, offering more project depth than the compact ELEGOO kit without the storage burden of the 365-piece option.
- The 82-piece and BOJACK kits solve different size problems: the former emphasizes male and female headers across five board sizes, while BOJACK offers six board sizes but places less emphasis on connector variety.
- The 58-piece kit is the specialist choice for screw-terminal builds, whereas ELEGOO makes more sense as a compact board refill than as a complete learning set.

More Details on Our Top Picks
Electronics Component Fun Kit with E-Book
I rank the Electronics Component Fun Kit as the strongest starting point for readers who need instruction alongside hardware. Its breadboard-to-solder workflow lets a learner assemble temporary circuits before committing them to a PCB, while the included e-book supplies more direction than the Smraza 104pcs PCB Board Kit. Compatibility with Arduino, Raspberry Pi, ESP32, and ESP8266 also leaves room to try several controller families. The tradeoff is specialization: this is a broad electronics starter package, not a deep perf-board assortment. Smraza provides more board sizes and connector options for repeated permanent builds. Component quantities, breadboard dimensions, and e-book coverage are not specified either. I place it here because its guided learning path is more useful to a first-time builder than receiving a larger pile of undocumented boards.
Pros:- E-book gives new builders a structured entry point
- Supports both temporary breadboard work and soldered PCB projects
- Compatible with four popular microcontroller and single-board computer platforms
- Includes core components such as LEDs, resistors, and jumper wires
Cons:- Quantities and dimensions for the included components are not supplied
- Offers less PCB size variety than the Smraza and 58-piece board kits
- More complex projects will require extra components and connectors
Best for: First-time electronics learners who want to move from breadboard experiments to basic soldered microcontroller projects
Not ideal for: Experienced builders who already own components and need a large, clearly quantified supply of perf boards
- Prototyping platform:Breadboard
- Wiring included:Jumper wires
- Output components:LEDs
- Passive components:Resistors
- PCB supplies:Soldering kit
- Learning material:E-book
- Microcontroller compatibility:Arduino, ESP32, ESP8266
- Single-board computer compatibility:Raspberry Pi
Our verdict“I recommend this kit to beginners who value guided learning more than a large inventory of prototype boards.”
Smraza 104pcs Double Sided PCB Board Kit
The Smraza 104pcs PCB Board Kit earns its position by balancing board choice, connectors, and manageable quantity. Its 31 boards span five sizes, giving most Arduino builders enough flexibility for sensor nodes, control panels, and compact modules without the storage burden of the 174-Piece PCB Circuit Board Prototype Kit. Straight, right-angle, and female headers also make the package more adaptable than a board-only refill. I particularly like the 300V, 16A terminal rating for projects that need sturdier external connections, though that rating does not make an assembled hobby board safe for mains wiring. The weaknesses are limited guidance and fewer boards than the larger assortments. Builders must also supply soldering equipment and project-specific parts. I rank it as the best-balanced selection, not the largest or most beginner-friendly one.
Pros:- Five PCB sizes cover compact modules and larger control circuits
- Includes straight, right-angle, and female 40-pin headers
- Screw terminals support removable field wiring
- Six jumper-cap colors aid visual organization
Cons:- Only 31 PCB boards despite the 104-piece total
- Assembly guidance is sparse
- Soldering tools and active electronic components must be purchased separately
Best for: Arduino hobbyists who want several practical board sizes plus common interconnect hardware in one organized purchase
Not ideal for: High-volume builders who consume prototype boards quickly or beginners who need step-by-step project lessons
- Total kit size:104 pieces
- PCB board count:31
- Board sizes:2x8cm, 3x7cm, 4x6cm, 5x7cm, 7x9cm
- Header connectors:40-pin male, right-angle male, and female
- Screw terminal pitch:5.08mm
- Screw terminal rating:300V, 16A
- Jumper caps:30 caps across 6 colors
Our verdict“I see this as the practical middle choice for builders who want useful variety without buying the largest assortment.”
174-Piece PCB Circuit Board Prototype Kit
I give the 174-Piece PCB Circuit Board Prototype Kit the top position because it pairs the broadest listed inventory with durable, assembly-friendly boards. The FR4 construction and pre-tinned holes support cleaner solder flow and repeated handling, while mounting holes make finished prototypes easier to secure inside enclosures. Compared with the Smraza 104pcs kit, this package offers a larger supply and more jumper caps; compared with the 58-Piece PCB Circuit Prototype Kit, it lists both 5.08mm terminal blocks and multiple header orientations. That range suits builders maintaining several projects at once. Its scale is also the main drawback: occasional users may pay for parts that sit unused, and there are no detailed assembly instructions. The fixed 2.54mm grid will not directly accept every surface-mount or unusual-pitch component. Even so, its depth and build-ready hardware make it my most capable all-around pick.
Pros:- Large assortment supports numerous simultaneous or repeat builds
- FR4 boards resist flexing better than low-grade paper-based boards
- Pre-tinned holes reduce soldering friction
- Includes headers, terminal blocks, mounting holes, and 100 jumper caps
Cons:- Large inventory may be wasteful for occasional projects
- No detailed assembly instructions are included
- Fixed 2.54mm layout limits direct use with unusual-pitch components
Best for: Frequent Arduino and electronics builders who maintain multiple prototypes and want boards, headers, terminals, and jumpers stocked together
Not ideal for: Occasional makers with limited storage or projects centered on surface-mount and non-2.54mm-pitch components
- Listed PCB board count:174
- Board size range:Up to 3.5×5.9 inches
- Board material:FR4 fiberglass
- Board thickness:1.6mm
- Hole finish:Pre-tinned
- Pin pitch:2.54mm (0.1 inch)
- Header sets:6 male, 6 female, 4 right-angle
- Terminal blocks:6 two-pin and 4 three-pin
- Jumper caps:100
Our verdict“I recommend this set to active builders who will benefit from its large inventory and broad connection hardware.”
82 Piece Double Sided PCB Board Kit
The 82 Piece Double Sided PCB Board Kit is my connector-focused choice for circuits that need many plug-in modules or detachable wires. Eight straight male, eight right-angle male, and eight female 40-pin headers offer far more pins than most single projects require, while 14 terminal blocks support tidy external connections. Compared with the 58-Piece PCB Circuit Prototype Kit, this set supplies jumper caps and a clearly itemized connector mix; the Smraza 104pcs kit, however, provides more PCB boards and a higher 16A terminal rating. The double-sided FR4 boards and tin-plated holes are suited to durable prototypes, but only 19 of the 82 pieces are boards. New builders may also find the connector volume mismatched to their needs. I rank it below the broader kits because its connection-first assortment serves a narrower, though useful, purpose.
Pros:- Generous supply of three different 40-pin header styles
- Fourteen screw terminal blocks support detachable wiring
- Five board dimensions accommodate several circuit footprints
- FR4 construction and tin-plated holes aid durable soldered builds
Cons:- Only 19 PCB boards are included in the 82-piece package
- Connector-heavy mix may leave casual users with many unused parts
- Largest supplied board is limited to 70x90mm
Best for: Builders making modular Arduino controllers, test fixtures, or interface boards that use many headers and removable screw connections
Not ideal for: Beginners seeking guided projects or high-volume users who need more than 19 prototype boards
- Total kit size:82 pieces
- PCB board count:19
- Board sizes:20x80mm, 30x70mm, 40x60mm, 50x70mm, 70x90mm
- Board material:FR4
- Board thickness:1.6mm
- Header connectors:8 male, 8 right-angle male, 8 female; each 40-pin
- Screw terminal blocks:8 two-pin and 6 three-pin
- Jumper caps:25 across 5 colors
Our verdict“I favor this kit for modular builds where header and terminal availability matters more than raw board quantity.”
58-Piece PCB Circuit Prototype Solder Board Kit
I chose the 58-Piece PCB Circuit Prototype Solder Board Kit for builders who value board quantity and footprint choice over accessory breadth. Its six dimensions include a useful 6x8cm option absent from the Smraza 104pcs PCB Board Kit, and the stated 58-board supply exceeds Smraza’s 31 boards. Standard 2.54mm holes and headers fit many through-hole components and Arduino-oriented modules, while two- and three-pin terminals simplify power or sensor wiring. The tradeoff is a leaner accessory mix: no jumper caps are listed, and its terminals are rated at 10A rather than Smraza’s 16A. Buyers also need to verify board dimensions and pin arrangements before ordering, since the kit does not solve every layout. With 1.6mm boards and organized packaging, this is my board-first refill choice for repeated medium-size prototypes.
Pros:- Six board sizes provide the widest stated footprint selection in this batch
- Fifty-eight boards support repeated prototyping
- Standard 2.54mm spacing suits common through-hole parts
- Includes male and female headers plus two terminal configurations
Cons:- No jumper caps are listed
- Terminal current rating is lower than the Smraza kit’s 16A rating
- Buyers must verify dimensions and pin configurations against each design
Best for: Regular through-hole builders who need many medium-size perf boards and already own soldering tools and loose components
Not ideal for: Projects requiring high-current terminals, jumper-cap configuration, or component pitches other than 2.54mm
- PCB board count:58
- Board sizes:2x8cm, 3x7cm, 4x6cm, 5x7cm, 6x8cm, 7x9cm
- Hole diameter:1mm
- Hole pitch:2.54mm
- Board thickness:1.6mm
- Header format:40-pin male and female, 2.54mm pitch
- Screw terminal pitch:5mm
- Screw terminal rating:300V, 10A
- Terminal pin options:2-pin and 3-pin
Our verdict“I recommend this kit as a board-focused refill for frequent through-hole projects that do not need a large jumper assortment.”
ELEGOO 32 Pcs Double Sided PCB Board Prototype Kit
I rank the ELEGOO 32-piece kit as the best organized board assortment because its five sizes cover varied circuit footprints, while the plastic tray keeps spare boards sorted. The pre-tinned plated holes reduce solder preparation, and 1.6mm FR4 gives permanent projects a sturdier foundation than a temporary breadboard. Compared with the BOJACK 40-piece kit, ELEGOO supplies eight fewer boards and one fewer size, so it loses on sheer quantity. Its advantage is a more clearly specified board thickness, convenient storage, and solder-friendly hole finish. This remains a board-only package, unlike the 365Pcs kit with wires and connectors, so buyers must already own headers and terminals. I would choose it for orderly, repeat soldering work, but not for advanced designs requiring documented electrical tolerances.
Pros:- Five board sizes accommodate both compact and moderately sized circuits
- Pre-tinned plated holes reduce solder preparation
- 1.6mm FR4 construction provides a rigid base for permanent prototypes
- Plastic storage tray keeps the 32 boards organized
Cons:- Includes fewer boards and size choices than the BOJACK 40-piece kit
- Provides no headers, jumper wires, terminals, or electronic components
- Electrical properties and tolerances are not documented
Best for: Arduino hobbyists who already own components and want a neatly stored assortment of solder-ready FR4 boards
Not ideal for: Advanced circuit designers who need documented electrical properties or buyers seeking wires, headers, and terminals in the same package
- Board count:32
- Board construction:Double-sided
- Material:FR4 glass fiber
- Board thickness:1.6mm
- Size selection:5 sizes
- Hole finish:Pre-tinned plated holes
- Mounting holes:4 at each corner
- Storage:Plastic tray
Our verdict“Choose ELEGOO when organized storage and solder-ready boards matter more than maximum quantity or bundled accessories.”
BOJACK 6 Values 40 Pcs Double Sided PCB Board Prototype Kit
The BOJACK 40-piece kit earns my bulk-selection role by pairing the highest board count in this batch with six clearly listed sizes. That range lets frequent builders reserve small boards for sensor nodes and larger 7x9cm boards for circuits needing more routing room. Compared with the ELEGOO 32-piece kit, BOJACK provides eight extra boards and an additional size, making it the stronger choice when quantity and footprint flexibility lead the decision. The tradeoff is less supporting detail: no thickness or electrical ratings are supplied, and the package contains no connectors or guidance. It also falls behind the 365Pcs kit for buyers starting without a parts drawer because wires, headers, and terminals must be purchased separately. I rank it for experienced Arduino and IoT builders who want economical board inventory, not a guided starter set.
Pros:- Forty boards provide ample stock for repeated builds and revisions
- Six sizes offer the broadest footprint selection among these three products
- FR-4 glass fiber construction suits durable soldered prototypes
- Four mounting holes per board simplify enclosure installation
Cons:- No jumper wires, headers, terminals, or other assembly parts are included
- No instructions are provided for new builders
- Board thickness and electrical ratings are unspecified
Best for: Frequent Arduino and IoT builders who already have soldering supplies and need many perf boards across six footprints
Not ideal for: First-time solderers who need project instructions, connectors, jumper wires, or documented board thickness
- Board count:40
- Board construction:Double-sided
- Number of sizes:6
- Board sizes:2x8cm, 3x7cm, 4x6cm, 5x7cm, 6x8cm, 7x9cm
- Material:FR-4 glass fiber
- Mounting holes:4 per board
- Project compatibility:Arduino and IoT projects
- Included contents:PCB boards only
Our verdict“Buy BOJACK when board quantity and six-size flexibility outweigh the need for accessories or beginner guidance.”
365Pcs Double Sided PCB Board Kit
I give the 365Pcs Double Sided PCB Board Kit the all-in-one role because it combines 20 boards with jumper wires, headers, caps, and screw terminals. Those additions reduce separate purchases and make the package better suited to complete soldered assemblies than either the ELEGOO or BOJACK board-only assortment. Its 205 jumper wires support tidy point-to-point routing, while multiple header styles and terminal blocks make removable modules and external wiring easier to plan. The compromise is board inventory: compared with the BOJACK 40-piece kit, this set provides half as many boards and only four sizes. The 365-part count also sounds more expansive than the PCB supply itself because most pieces are small interconnect components. I favor it for builders assembling varied projects from a single box, though complete newcomers may struggle without instructions.
Pros:- Combines prototype boards, jumper wires, headers, caps, and terminal blocks
- Four board sizes support several common circuit footprints
- Straight, female, and right-angle headers accommodate different mounting layouts
- Screw terminals provide practical connections for external wiring
Cons:- Only 20 PCB boards are included despite the 365-piece headline
- Offers fewer board sizes and boards than the BOJACK kit
- Large parts assortment comes without project or assembly instructions
Best for: Arduino builders and repair hobbyists who need boards, interconnect wiring, headers, and screw terminals in one purchase
Not ideal for: High-volume prototypers who need more than 20 boards or complete beginners seeking guided projects and assembly instructions
- PCB board count:20, with 5 per size
- Board construction:Double-sided
- Board sizes:2x8cm, 3x7cm, 4x6cm, 5x7cm
- U-shaped jumper wires:140
- Flexible jumper wires:65
- Jumper caps:120 in 6 colors
- Header connectors:3x 40-pin male, 3x 40-pin female, 3x right-angle male
- Screw terminal blocks:10 total: 5x 301-2P and 5x 301-3P
- Terminal rating:300V/16A
Our verdict“Pick this kit when a ready supply of interconnect parts is more useful than the larger board inventory offered by board-only rivals.”
How We Picked
I treated these products as physical circuit-prototyping kits, since they contain perfboards and assembly parts rather than PCB layout software or custom board-manufacturing tools. My evaluation weighted board-size usefulness, connector selection, project coverage, learning support, and the likelihood that the included pieces would serve several builds. I also separated meaningful variety from raw quantity: 365 pieces can be attractive, but that number matters less if many parts duplicate items a buyer already owns.
My ranking places the 174-piece kit first for its balanced assortment, followed by the beginner-oriented Electronics Component Fun Kit and the value-focused Smraza set. The 365-piece bundle ranks next as the premium inventory choice, followed by the 82-piece header set, the 58-piece screw-terminal kit, BOJACK’s six-size assortment, and ELEGOO’s compact 32-piece pack. Lower-ranked products are not poor choices; they have narrower use cases or sharper compromises. I favored kits that can support several prototype layouts without forcing buyers to purchase basic connectors immediately afterward.
Factors to Consider When Choosing Best PCB Design Kits
Choosing among these kits starts with identifying where the circuit will be in its development cycle. I would buy a learning bundle for experimentation, a varied perfboard set for repeated permanent builds, or a connector-specific kit for finished enclosures. The following factors help separate useful inventory from surplus parts.
Distinguish Circuit Learning From PCB Layout Work
These products support breadboarding, soldering, and permanent prototyping, but they do not replace PCB design software. A breadboard lets a builder revise a circuit without solder, while perfboard turns a proven layout into a sturdier assembly using point-to-point wiring or solder bridges. I would start with the Electronics Component Fun Kit when the circuit itself is still being learned. Builders who already have components and a working schematic gain more from the 174-piece, Smraza, or 365-piece board assortments. A common mistake is buying a large perfboard bundle and expecting printed copper traces tailored to a project. Anyone planning a manufactured board will still need electronic design automation software and a fabrication service.
Match Board Dimensions To Real Projects
Board-size variety matters more than the largest included board for buyers who build different devices. Small boards suit sensors, adapters, and power modules, while larger boards leave room for microcontrollers, connectors, and cleaner wire routing. I would choose the BOJACK kit when six physical sizes are more useful than a large connector assortment. The 82-piece kit trades one size tier for male and female header flexibility, which can be better for modular Arduino work. Oversized perfboard wastes enclosure space, but a cramped board creates difficult solder joints and poor repair access. Before buying, I would sketch the component footprints and reserve extra room around power parts, mounting holes, and external connectors.
Choose Connectors Around Maintenance Needs
Headers and screw terminals create different kinds of serviceability. Male and female headers work well for shields, removable modules, and swappable microcontrollers, but they are less convenient for loose field wiring. Screw terminals provide a firmer connection for power leads, motors, switches, and enclosure-mounted devices. I would favor the 58-piece kit for installations that may need wires disconnected during maintenance, even though its smaller count limits general inventory depth. For stackable electronics, the 82-piece header kit is the more adaptable choice. Buyers often focus on board quantity and later spend extra money on the connectors that determine whether the finished device is easy to repair.
Judge Piece Counts By Usable Variety
A 365-piece label does not automatically mean 365 distinct project opportunities. Counts may include every header strip, terminal, or repeated board as a separate piece, so I would examine the assortment breakdown before comparing totals. High-count kits make sense for clubs, classrooms, and frequent builders who consume the same sizes repeatedly. A focused set such as Smraza’s 104-piece kit is easier to store and may leave less idle inventory for an occasional hobbyist. The compact ELEGOO bundle is better viewed as a refill for someone who already owns components and connectors. I would pay more for the 365-piece kit only when repeated builds can justify both its volume and storage needs.
Account For Skill Level And Supporting Supplies
A perfboard kit rarely contains the whole soldering workflow. Beginners may still need a temperature-controlled iron, solder, flux, cutters, wire, a multimeter, and a safe work surface. The Electronics Component Fun Kit reduces the learning gap by pairing a breadboard and instructional material with basic components, making circuit verification possible before soldering. By comparison, ELEGOO’s smaller board bundle assumes the buyer already knows how to translate a working circuit onto perfboard. I would also check whether headers arrive loose or require cutting, since that task adds preparation and can produce uneven ends. Paying for guided material is worthwhile for a first project, while experienced builders usually gain more from additional board sizes and connector types.
Frequently Asked Questions
Do These PCB Design Kits Include Software For Creating Custom Circuit Boards?
No; these are physical prototyping and soldering kits, not software packages for routing manufactured PCBs. Their double-sided perfboards use a regular hole grid, so the builder creates connections with leads, wire, or solder bridges. Custom copper traces, ground planes, and fabrication files require separate electronic design automation software. I would choose one of these kits for turning a tested breadboard circuit into a durable prototype. For production-ready boards, I would use the kit during validation and then recreate the circuit in PCB layout software.
Which Kit Makes The Most Sense For A Complete Beginner?
The Electronics Component Fun Kit is my beginner recommendation because its e-book, breadboard, jumper wires, LEDs, and resistors support learning before permanent soldering. That staged process makes mistakes easier to find and cheaper to correct. The ELEGOO kit costs less in complexity, but its board-focused contents are better suited to someone who already has components and basic soldering knowledge. A beginner should still budget for tools and safety equipment that are not clearly listed with the kit. Once several circuits have been completed, a larger perfboard assortment becomes a more useful next purchase.
Is The 365-Piece Kit Automatically Better Than The Smaller Sets?
No; inventory depth and project fit matter more than the headline count. The 365-piece kit is my premium choice for frequent builders, shared workspaces, or buyers who expect to consume many repeat parts. The 174-piece kit ranks higher overall because its more moderate assortment should suit a broader range of individual buyers without creating as much unused stock. Smraza’s 104-piece set is a better value target for occasional projects. I would check the quantity of each board size and connector before paying extra for the largest package.
How Many Perfboard Sizes Do I Actually Need?
Most hobbyists can cover routine sensor, controller, and adapter projects with three to five practical board sizes. More sizes help when enclosures are already chosen or when small modules must fit into tight spaces. BOJACK’s six-size kit is the strongest match for buyers who prioritize dimensional choice, while the 82-piece kit gives up some size range in exchange for more explicit male and female header support. I would measure the intended enclosure and lay out the largest components before choosing. Leaving space around connectors and mounting points is usually more useful than selecting the smallest board that can hold every part.
When Are Screw Terminals Better Than Pin Headers?
Screw terminals are better for removable external wiring, including power inputs, motors, pumps, switches, and longer cable runs. They accept bare wire without requiring a matching plug, which makes installation and later servicing simpler. Pin headers are more compact and work better for boards, modules, and ribbon-style connections inside an enclosure. The 58-piece kit is my specialist recommendation when terminal-based wiring is central to the project, while the 82-piece kit better serves modular header connections. For mixed systems, I would select the kit covering the harder-to-source connector and buy ordinary perfboard separately if needed.
Conclusion
For most builders, I recommend the 174-Piece PCB Circuit Board Prototype Kit as the best overall choice because it offers the strongest balance of boards and headers without leaning entirely on bulk quantity. The Smraza 104pcs Kit is my best value pick for occasional projects, though buyers needing guided instruction should choose the Electronics Component Fun Kit instead. That e-book-equipped set is the best option for beginners, while the 365-piece bundle is the premium choice for frequent builders who can use and store a deeper inventory. Choose the 82-piece kit for male and female header flexibility, the 58-piece kit for screw-terminal projects, or BOJACK when six board sizes are the priority. ELEGOO’s 32-piece set makes the most sense as a compact refill for an established workbench, but its limited breadth makes it easier to outgrow. My final choice would follow the current project stage: learn with the Electronics kit, build varied prototypes with the 174-piece set, or stock a busy bench with the 365-piece bundle.
