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
- 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
Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
