Upgrade your prototyping experience with the MB102 Breadboard Dedicated Power Supply Module. Designed for hobbyists, educators, and engineers, this compact mini module delivers reliable 3.3 V and 5 V power directly to your solderless breadboard, eliminating the need for bulky external adapters. Its sleek black‑white design and micro‑USB connection make it the perfect addition to any electronics workspace.
Product Overview
The MB102 power supply module fits snugly onto a standard 830‑point breadboard, providing clean, regulated voltage to both rails simultaneously. With dual output options and built‑in protection features, you can focus on building and testing circuits without worrying about power stability.
Key Features
- Dual voltage outputs: selectable 3.3 V and 5 V for versatile circuit design.
- Micro‑USB power input (5 V ± 0.5 V) for easy connection to chargers, power banks, or wall adapters.
- Compact mini form factor – fits perfectly on a standard MB‑102 breadboard.
- On‑board voltage regulators (AMS1117) ensure low ripple and high efficiency.
- Built‑in over‑current and short‑circuit protection for added safety.
- Clear LED indicators show power status for each voltage rail.
- Solderless installation – simply plug into the breadboard’s power rails.
Compatibility
Designed for the popular MB‑102 solderless breadboard, this module works seamlessly with Arduino, Raspberry Pi Pico, ESP8266/ESP32, and a wide range of microcontroller development boards. It also supports any prototype that requires stable 3.3 V or 5 V power directly on the breadboard.
