MB-102 830-Hole Solderless Breadboard — Color-Coded Power Rails for Precision Prototyping
The MB-102 830-hole solderless breadboard with red and blue power rail markings is the benchmark prototyping tool for electronics engineers, Arduino developers, and STEM educators. Its full-length color-coded bus strips eliminate wiring errors before they happen — red for positive, blue for negative, every time.
Whether you're building a voltage divider, wiring up a sensor array, or testing a new microcontroller breakout, the MB-102 gives you 830 tie points of reliable, solder-free workspace in a compact 165×55mm footprint.
Key Features
- 830 tie points — ample space for multi-IC circuits, sensor networks, and power management stages
- Color-coded power rails — full-length red (+) and blue (−) dual-row bus strips for clear, error-free power distribution
- Standard 2.54 mm (0.1") pitch — accepts all DIP ICs, resistors, capacitors, transistors, LEDs, and standard jumper wires without adapters
- Interlocking side connectors — join multiple boards horizontally to expand your prototyping surface
- Durable ABS plastic housing — rigid, non-conductive body with self-adhesive backing for stable bench mounting
- Nickel-plated spring contacts — low-resistance contacts maintain reliable connection across hundreds of insertion cycles
- Available with retail packaging — choose the standard board or the packaged version for gifting or classroom distribution
Variant Options
- 830 Hole — bare board, ready to use immediately
- 830 Hole Packaging — same board in retail box packaging, ideal for kits, gifts, and educational bundles
Ideal Applications
- Arduino UNO, Nano, and Mega project development

Frequently Asked Questions
Q: What is the difference between the two variants?
A: Both variants are identical MB-102 830-hole breadboards. The "830 Hole Packaging" variant includes retail box packaging, making it ideal for gifts, classroom kits, or resale bundles.
Q: Are the red and blue lines just cosmetic?
A: No — the red and blue strips indicate the positive (+) and negative (−) power bus rails respectively. They are functional guides that help you wire power connections correctly and avoid polarity errors.
Q: Can I connect multiple boards together?
A: Yes. The MB-102 features interlocking side connectors that allow you to snap multiple boards side-by-side, creating a larger continuous prototyping surface for complex projects.
Q: Is this compatible with 3.3V and 5V systems?
A: Yes. The MB-102 supports both 3.3V (ESP32, Raspberry Pi) and 5V (Arduino UNO) logic levels without modification.
