Relay for micro:bit
The MonkMakes Relay for micro:bit is a solid-state (no moving parts) relay that allows an output of a micro:bit to turn things on and off.
This relay 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 relay will automatically protect itself against too much current,
Please note that the individual boards are packed in antistatic bubblewrap bags.
