A solid-state (no moving parts) relay that allows an output of a micro:bit to turn things on and off. A micro:bit can turn an LED on and off directly, but anything more powerful re quires something like a relay. 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. Features Solid-sate relay (up to 2 Amps) Active LED indicator Resettable ‘polyfuse’ to protect against over-current Specifications: Data Sheet User Guide: Show more
