MB-102 Breadboard Power Supply Module 5V 3.3V USB & DC Input
MB-102 Breadboard Power Supply Module — Dual Output 5V & 3.3V
Power your electronics prototyping projects with confidence using the MB-102 Breadboard Power Supply Module. Designed to plug directly into standard 830-point or 400-point breadboards, this compact module delivers clean, stable 5V and 3.3V dual outputs — giving you the flexibility to power virtually any microcontroller, sensor, or component in your circuit.
Whether you're a hobbyist building your first Arduino project, a student working on a school assignment, or an experienced engineer prototyping a new circuit, the MB-102 makes bench power supply setup fast, easy, and reliable.
Key Features
- Dual Input Options: USB Micro port (5V) or DC-005 barrel jack (6.5V–12V input) — use whichever power source is most convenient
- Dual Voltage Outputs: Independently selectable 5V or 3.3V on each of two power rails via onboard jumpers
- Direct Breadboard Fit: Slides directly onto standard MB-102 breadboards; red (+) and blue (−) power rails connect instantly — no wiring required
- Onboard Power Switch: Conveniently toggle power on/off without disconnecting your circuit
- LED Power Indicator: Visual confirmation that the module is active and supplying power
- Max Output Current: Up to 700mA per channel — suitable for most microcontrollers (Arduino, ESP8266, Raspberry Pi Pico, etc.) and peripheral sensors
- Compatible with Most Power Adapters: Works with standard 9V or 12V DC wall adapters via the DC-005 round-hole connector
- Compact & Lightweight: Minimal footprint keeps your workspace tidy and your breadboard accessible

Frequently Asked Questions
Q: What breadboards is the MB-102 Power Supply Module compatible with?
A: The MB-102 Breadboard Power Supply Module is designed to fit standard MB-102 breadboards, including common 830-point and 400-point versions. It plugs directly into the breadboard's power rails via its red (+) and blue (−) pins, eliminating the need for extra jumper wires to supply power.
Q: Can I use a USB power bank or phone charger to power the MB-102 module?
A: Yes! The Micro USB input accepts any standard 5V USB power source — including USB wall chargers, power banks, and computer USB ports. This makes it extremely versatile for both desktop prototyping and portable project setups.
Q: How do I select between 5V and 3.3V output on the MB-102?
A: Each of the two output rails has an onboard jumper that lets you independently select 5V or 3.3V output. Simply move the jumper to the desired position for each rail before powering on your circuit. This dual-rail configuration lets you simultaneously power 5V and 3.3V components from the same module.
