SHILLEHTEK MB102 Breadboard Power Supply Module 3.3V/5V Arduino

The ShillehTek MB102 Breadboard Power Supply Module makes it easy to power a standard MB102-style breadboard with stable 3.3V and 5V rails for Arduino-compatible projects, sensors, and quick prototypes. Instead of juggling loose jumper wires from a USB cable or a bench supply, you plug this module into the breadboard power header and select 3.3V or 5V per rail with simple jumpers or switches (depending on the version). It is perfect for powering sensors, small microcontrollers, and test circuits cleanly while you develop and debug.
