Product Description

DF Robot Circular RGB LED Expansion Board for the BBC micro:bit

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 a tomato timer via the onboard buzzer, and turn it into a colorful music 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. 

With different paper-cuts and acrylics, you can put on a variety of new clothes for the expansion board. For example, put on red Chinese knot for it in Chinese New Year, put on the cartoon face for it at Children's Day, put on the snow or Christmas tree for it at Christmas.
