BOJACK 37 Values 480 Pcs Electronics Component Fun Kit with
✅ PROS
- 480 components across 37 values means you can finish most breadboard projects without a second order
- Components are individually labeled and sorted in a divided case — no digging through a bag of mixed resistors
- Includes a 65W power supply module and jumper wires, saving $15–20 versus buying them separately
❌ CONS
- The storage case is functional but flimsy; the latch feels like it will break after a few dozen opens
- Resistor tolerance is 5% (not 1%), which matters for precision analog circuits — fine for Arduino work, not for audio filters
The Verdict
If you’re tired of ordering a $4 bag of resistors and waiting three days for shipping every time a project needs one more 10kΩ, the BOJACK 37 Values kit is built for you. This is the starter kit that actually covers a full semester of hobby electronics — not the “37 pieces” garbage some brands try to pass off. BOJACK gives you 480 components, and the math works out to roughly 13 pieces per value group. That’s enough to breadboard, prototype, and make mistakes without rationing parts.
What’s actually in the box
The kit arrives in a clear, double-layer plastic case with 37 labeled compartments. As shown in the product image, each compartment holds a specific component type — resistors from 10Ω to 1MΩ, capacitors from 10pF to 100µF, diodes, transistors, LEDs in five colors, potentiometers, and a handful of ICs. You also get a 65W power supply module (the one with the barrel jack and screw terminals), a 40-pin male-to-male jumper wire set, and a small breadboard. The included components list on the back of the box is accurate — I counted 480 pieces and it matched.
Real-world performance
I’ve run two full Arduino projects with this kit: a temperature logger with an OLED display and a motor controller with an H-bridge. The components performed exactly as expected. The 5mm LEDs are bright and consistent, the 2N2222 transistors switch cleanly, and the ceramic capacitors have proper markings — no mystery parts. The jumper wires are solid-core and hold their shape nicely in breadboards, which is more than I can say for cheaper kits where the wires bend permanently after one insertion.
The power supply module is a genuine outlier in this price range. It steps down from a 9V battery or wall adapter to a regulated 5V output with decent current handling. One reviewer noted, “The power module alone is worth half the price of this kit — it’s the same one sold separately for $12.” That checks out.
What buyers consistently praise
The organization is the standout feature. Multiple reviewers mention the labeled compartments as the reason they chose this over competitors. One customer wrote, “I can find a 100nF capacitor in five seconds without dumping everything on the desk.” Another said, “The value labels on the resistors are actually readable — my eyes aren’t what they used to be, and I didn’t need a magnifying glass.”
Where it falls short
The storage case is the weak link. The latch is thin plastic and the hinge feels like it will crack if you’re rough with it. If you plan to carry this in a backpack, wrap it in something — the case won’t survive a drop from desk height without popping open.
The 5% resistor tolerance is the other honest limitation. For digital logic and most microcontroller work, that’s completely fine. But if you’re building precision analog circuits — voltage dividers for sensors, audio filters, or anything requiring tight tolerance — the actual resistance can vary noticeably. Buy 1% resistors separately for those projects.
The IC selection is also limited: you get a few 555 timers, an LM358 op-amp, and a couple of logic chips, but nothing exotic. That’s not a flaw — it’s the right scope for a beginner kit.
Who should buy this
This kit is ideal for three types of people: students taking an introductory electronics course, hobbyists who want to follow Arduino tutorials without ordering parts piecemeal, and makers who need a reliable bench stock of common components. It’s also a solid gift for a teenager showing interest in electronics — the variety keeps them engaged without the frustration of running out of parts mid-project.
Skip it if you’re building precision audio gear, if you already have a well-stocked component drawer, or if you expect a rugged, travel-ready case. Also skip if you need SMD components — this is through-hole only.
FAQ
Q: Does this kit include an Arduino or Raspberry Pi? A: No. It includes the power supply module, breadboard, jumper wires, and components, but no microcontroller board. You’ll need to supply your own Arduino Uno or similar.
Q: Are the components sorted by value or mixed together? A: Sorted. Each of the 37 compartments holds one value group, with labels on both the case lid and the compartment dividers.
Q: Can I use this kit for a college electronics lab course? A: Mostly yes. It covers resistors, capacitors, diodes, transistors, and common ICs — enough for introductory labs. But check your syllabus; some courses require specific ICs or precision components not included here.
The Verdict
Buy it if you’re starting electronics, teaching someone else, or you’re tired of ordering components one at a time. Skip it if you need precision components or a rugged storage solution.
Rating: 4.6/5 — The component quality and organization earn the high score. The case durability and resistor tolerance keep it from being perfect. At this price, it’s the best value starter kit I’ve tested, and the included power supply makes it a complete workspace starter set.
