The MB102 Breadboard Power Supply Module is a compact plugin adapter designed to provide regulated 3.3V and 5V DC power directly to solderless breadboards. Featuring dual independent channels, each side can be manually configured via jumpers to output 3.3V, 5V, or turn completely off. It accepts a wide 6.5V to 12V DC input via a standard barrel jack or can be powered directly via its USB port. Equipped with an on/off tactile switch and an LED indicator, it provides up to 700mA of clean, stable current—making it an essential tool for clean and safe Arduino, ESP32, and DIY electronics prototyping.
