The sensor:bit is a breakout board for the BBC micro:bit that extends all available I/O ports into standard GVS (Ground-Voltage-Signal) pin headers. This makes it easy to connect 3 V electronic modules like LEDs, photocells, servos, and other sensors without a breadboard. The board also features a built-in buzzer and audio jack for sound output.
With 16 GVS channels, dedicated I2C headers (compatible with OLED displays, BME280, etc.), and LEGO-compatible mounting points, sensor:bit is a versatile expansion platform for micro:bit projects.
Key Features
- 16-Channel GVS Ports – Standard 3-pin headers for connecting 3 V modules
- Built-In Buzzer – Controlled via P0; auto-disconnects when headphones are plugged in
- 3.5 mm Audio Jack – Listen to micro:bit audio output through headphones
- Dedicated I2C Headers – Both male and female for OLED, BME280, and other I2C devices
- LEGO Compatible – Mounting interface for LEGO builds
- Silk-Screen Labelled – Each I/O port clearly marked on the board
Specifications
- SKU – EF03415
- Version – V1.6
- Working Voltage – 2.7–3.3 V
- Dimensions – 57 × 42 mm
- Weight – 18 g
Ideal For
- Expanding micro:bit I/O for sensor and actuator projects
- Music and sound projects with buzzer or headphone output
- Connecting I2C displays and environmental sensors
- STEM education and classroom activities

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout board carries a small or fine-pitched component and brings its connections out to standard, breadboard- and header-friendly pins. Describing a part as a breakout means it can be wired into a project without soldering directly to the component's tiny contacts.
- Headers
- Rows of connector contacts on a fixed pitch (commonly 2.54 mm) used to link a board to a breadboard, jumper wires, or another board. They come as male pin headers and female socket headers; when a module ships with pre-soldered headers it can be used straight away, whereas bare pads require soldering the pins yourself.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- OLED
- OLED stands for organic light-emitting diode, a display type where each pixel produces its own light. It matters because OLED screens are thin, high-contrast and easy to read for small status displays, but they can be more sensitive to image burn-in than some other display types.
