Description
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.
Package contents
Includes 1 x MB102 Breadboard Power Module. Please note that breadboards and input power cables are not included.
