The ZIP Halo is a circular LED board for the BBC micro:bit featuring 24 individually addressable full-colour ZIP LEDs (WS2812B). Each LED can display a huge spectrum of colours, enabling vibrant rainbow effects, colour mixing, data visualisation, and animated light displays.

The board bolts securely onto the micro:bit using five bolts and provides a regulated power supply to the micro:bit via JST connector or solder pads. Pins P1 and P2 are broken out to 0.1″ pads along with power and GND for connecting additional sensors or switches.
