Low voltage relay for micro:bit (solid state)

Product DescriptionThe MonkMakes Relay for the BBC microbit is 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 requires something like a relay or a transistor. Using a transistor to switch something on and off requires a shared ground connection with the micro:bit and a knowledge of electronics that you or your students may not be ready for. The MonkMakes Relay for micro:bit is much easier to use, acting like a simple micro:bit controlled switch.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-state relay (No moving parts).
Resettable polyfuse to protect against over-current.
2A Maximum current.
16V Maximum voltage.
Integrated active LED power indicator.
