A dual-output breadboard power supply module that provides selectable 3.3 V and 5 V rails. Designed for use with the BBC micro:bit, Arduino, Raspberry Pi, and standard MB102 breadboards, it solves the common problem of the micro:bit lacking a 5 V output pin — essential when driving servos, ultrasonic sensors, and other 5 V modules.

Key Features

• Dual Output – Two independent power rails, each selectable between 3.3 V and 5 V via jumper caps
• Three Input Options – DC barrel jack (2.1 × 5.5 mm, 6.5–12 V), USB Type-A, or Micro USB
• Breadboard Compatible – Plugs directly into MB102 and standard breadboards
• Versatile Power Sources – Works with wall adapters, computer USB ports, or mobile phone chargers

Ideal For

• Providing 5 V power to sensors and servos alongside a micro:bit
• Breadboard prototyping with Arduino, Raspberry Pi, or micro:bit
• Projects requiring both 3.3 V and 5 V power rails simultaneously
