BBC Micro bit Prototype Expansion Board

This prototype expansion board breaks out all of the BBC micro:bit's edge connector pins to labelled headers and includes a small breadboard for building circuits. It provides a beginner-friendly way to learn electronics and programming with the micro:bit, making it easy to connect sensors, LEDs, motors, and other components.

The board supports multiple power supply options: external DC input (VIN or VCC), USB power via the micro:bit, or direct connection to the micro:bit's edge connector.

Key Features

  • Full Pin Breakout – Access to all micro:bit pins (P0–P20)
  • Built-in Breadboard – For prototyping circuits directly on the board
  • Multiple Power Options – External DC, USB, or micro:bit powered
  • Power Output Headers – VIN, 5 V, and 3.3 V output connectors

Specifications

  • Dimensions – 62 × 82 mm
  • Input Voltage – 6–24 V (VIN) or 3.6–6 V (VCC)
  • Digital Pins – P0–P20
  • Analogue Pins – P0, P1, P2, P3, P10
Power Supply Notes:
  • VIN (6–24 V): Use for external supplies above 6 V. Provides power output on VIN, 5 V, and 3.3 V headers.
  • VCC (3.6–6 V): Use for external supplies below 6 V. No power output on VIN or 3.3 V headers.
  • USB via micro:bit: Connect the micro:bit and power via USB. Only the 3.3 V header has power output; VIN and 5 V headers are inactive.

Package Contents

  • 1× Prototype expansion board for micro:bit
  • 1× Breadboard
