micro:bit Circular RGB LED Expansion Board

The micro:bit Circular RGB LED Expansion Board is an innovative extension for the micro:bit microcontroller, uniquely combining creativity and technology. With 24 RGB LEDs arranged in a circular layout, this board offers the opportunity to create colourful and dynamic lighting effects. It can be used as a cool clock, timer, wheel of fortune, portable jewelry, or interactive, colourful pendant. By integrating a microphone and a buzzer, it opens up new ways for musical and timed projects. In addition, the external P0 and P1 connections allow for expansion with a variety of sensors, making the possibilities nearly endless.
