MB102 Breadboard Power Supply Module, 3.3V 5V Dual Rail

This MB102 breadboard power supply module plugs directly into standard 5.5 cm width breadboards to deliver regulated power rails for prototyping. It accepts power via a DC barrel jack or USB port and provides independently switchable 3.3 V, 5 V, or 0 V outputs. It is an essential bench tool for students, makers, and electronics hobbyists powering microcontroller projects.

Dual independent power rails

The module features two independent output channels that can each be switched between 0 V, 3.3 V, and 5 V using onboard jumpers. It also includes two sets of dedicated header pins for powering external components directly.

Flexible power input options

Power the module using a standard 6.5 V to 12 V DC power supply jack or via a USB power connection. It delivers a maximum output current of up to 700 mA across your prototyping circuits.

Breadboard compatibility

Designed specifically for standard MB102 breadboards with a 5.5 cm width, fitting securely into the side power distribution rails.
