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
