The automation:bit is a micro:bit expansion board for controlling and monitoring low-voltage systems up to 24 V. It features analogue and digital inputs, sinking outputs, and a relay — all accessible via 3.5 mm screw terminals. No soldering required.
Program it using the block-based Microsoft MakeCode editor with the automation:bit library. Use micro:bit's buttons, LED matrix light sensing, or radio function with a second micro:bit as a remote control.
Key Features
- 24 V Relay – 1× relay with NC and NO terminals, rated at 2 A
- 3× ADC Channels – Analogue inputs with 0–24 V range
- 3× Buffered Inputs – 24 V tolerant digital inputs
- 3× Sinking Outputs – 24 V tolerant digital outputs
- 3.5 mm Screw Terminals – Secure, solderless wiring connections
- Fully Assembled – Ready to use, no soldering required
- MakeCode Support – Block-based programming via Microsoft MakeCode
Ideal For
- Home automation with micro:bit
- Low-voltage monitoring and control projects
- Learning about relays, inputs, and outputs
- STEM education and classroom automation
Package Contents

Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
