The Adafruit CRICKIT for micro:bit is a robotics and electronics driver board designed for the BBC micro:bit. Plug your micro:bit into the 40-pin edge connector and start controlling motors, servos, solenoids, NeoPixels, capacitive touch sensors, and a speaker — all managed over I2C via the Adafruit seesaw co-processor.

All outputs run at 5V DC, making it compatible with standard 5V servos, DC motors, steppers, solenoids, and relays. The power supply system includes a TPS2595 eFuse chip with over-voltage (5.5V), under-voltage (3V), and over-current (4A) protection, plus kick-back diodes on every motor driver.

Key Features

  • 4× Servo Outputs – Analogue or digital servo control with precision 16-bit timers
  • 2× DC Motor Drivers – Bi-directional, 1A current limit each, 8-bit PWM speed control (or 1 stepper motor)
  • 4× Darlington Drive Outputs – 500mA each with kick-back protection, for solenoids, relays, LEDs, or 1 unipolar stepper
  • 4× Capacitive Touch Sensors – Alligator-clip-friendly pads
  • 8× Signal Pins – Digital I/O or analogue inputs
  • 1× NeoPixel Driver – 5V level-shifted, connected to micro:bit pin #16 for MakeCode NeoPixel blocks
  • 1× Class D Audio Amplifier – 3W max, 4–8 ohm speaker, connected to micro:bit pin #1 (default audio output)
  • Seesaw I2C Co-Processor – Offloads all timers, PWM, and sensor management
  • eFuse Power Protection – Over-voltage, under-voltage, and 4A over-current protection
  • No Soldering Required – Plug in via 40-pin edge connector

Programming

  • MakeCode
  • Arduino
Note: MicroPython is not currently supported — only MakeCode and Arduino.

Also Available

Important: A BBC micro:bit and 5V power supply are required but not included. Use a 5V 2A supply for basic projects, or 5V 4A for running multiple motors/servos simultaneously. Only 5V components are supported — not for use with 9V or 12V motors.

Ideal For

  • Building robots and motorised projects with micro:bit
  • Interactive classroom projects with MakeCode
  • Adding motor and servo control to micro:bit creations
