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.

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- LiPo
- A lithium polymer rechargeable battery commonly used in portable electronics projects. It matters because LiPo batteries need correct charging circuitry and care, and this board includes hardware intended for that battery type.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
