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

Jargon buster
Plain-language definitions for the technical terms used above.
- 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.
- MicroPython
- A version of the Python programming language made to run on microcontrollers. It matters because it lets beginners write readable code to control LEDs, sensors, motors and displays without needing to start with lower-level languages.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- NeoPixel
- A type of addressable LED system where colour data is sent along a single digital data line from one LED or controller to the next. Compatibility matters because the timing and signal format must match for the lights or driver board to respond correctly.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- servo
- A servo is a motor with built-in position control, usually told to move to a specific angle by a control signal. It matters when you need repeatable movement, such as steering, arms, flaps, or linkages, rather than continuous spinning.
