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.
