This board can be a cool clock, a timer, a Lucky Turntable Game, a wearable ornament, and an interactive coloured pendant. With a micro:bit main board, this 24 RGB LEDs circular expansion board changes to an exquisite creator's piece.
You can turn it into an egg timer via the onboard buzzer, and turn it into a colourful spectrometer through the onboard microphone; There are two external ports P0, P1 in reserve, so you can get more ways to play by connecting a large number of boson and gravity sensors.
