The MonkMakes Switch for micro:bit is a solid-state (no moving parts) switch that allows an output of a micro:bit to turn things on and off.

This board can be used to switch low voltage devices such as light bulbs, a motor, a small heating element or even a string of 12V LED lighting. The voltage needs to be kept under 16V, but the switch will automatically protect itself against too much current.
