The MB102 breadboard power supply module is a compact, plug-in device that provides regulated 3.3V and 5V DC power directly to breadboard rails. It supports input voltages of 7-12V DC via a barrel jack or 5V via USB. Key features include independent voltage selection (3.3V/0V/5V) for both sides, a power switch, and a max output current of 700mA.�
These modules are essential for prototyping with components requiring different voltage levels, such as 3.3V sensors and 5V microcontrollers like Arduino.�
