Kitronik ZIP Halo - LED ring for BBC micro:bit

Description

Kitronik ZIP Halo is a circular expansion board for the BBC micro:bit, equipped with 24 individually addressable ZIP LEDs (RGB, compatible with WS2812B/NeoPixel). Each LED can display the full color spectrum, allowing for impressive animations, visualizations, and colorful lighting effects in educational and creative projects. The board is mounted directly to the micro:bit using five screws, ensuring a stable and solid connection. Additionally, the board provides access to P1 and P2 pins as well as power and ground (2.54 mm pitch), enabling the connection of additional components such as sensors or switches. Further expansion is possible by chaining additional ZIP LEDs.

The ZIP Halo is powered with a voltage range of from 3.5V to 5V, and the built-in regulator supplies the appropriate voltage to the BBC micro:bit. Power can be supplied via a JST connector (e.g., using a 3 × AAA battery pack or a LiPo battery) or by soldering wires directly to the pads. The LEDs are fully compatible with NeoPixel/WS2812B libraries, and programming is possible in the MakeCode editor (Blocks/JavaScript) or MicroPython.
