This circular expansion board with 24 RGB LEDs is a must - have for micro:bit enthusiasts. It can serve as a cool clock, a timer, a Lucky Turntable Game, a wearable ornament, or an interactive colored pendant. When paired with a micro:bit main board, it transforms into an exquisite creation. You can use the onboard buzzer to turn it into a tomato timer and the onboard microphone to make it a colorful music spectrometer. There are two external ports P0 and P1, allowing you to connect a wide range of boson and gravity sensors for more play options. You can also dress it up with different paper - cuts and acrylics, like a red Chinese knot during Chinese New Year, a cartoon face on Children's Day, or a snow or Christmas tree design at Christmas. It supports both USB interface power supply (from a power - bank or a USB computer) and PH2.0 interface power supply (with a battery box or lithium battery). With 24 RGB single - line lights offering 16 million colors for free mixing, Makecode graphical programming, an onboard microphone and buzzer, and led - out P0 and P1 interfaces with connection lines for boson expansion modules, its ultra - thin volume makes it perfect for wearable and strap applications. Supply Voltage ranges from 3.5 to 5V. It comes with a product wiki and more documents.




Using this circular RGB LED expansion board is easy. First, connect it to your micro:bit main board. You can power it up using a USB interface from a power - bank or your computer, or use the PH2.0 interface with a battery box or lithium battery. For different functions, if you want a tomato timer, use the onboard buzzer. To get a music spectrometer, rely on the onboard microphone. You can connect various boson and gravity sensors to the P0 and P1 ports for more fun. When it comes to dressing it up, just stick the paper - cuts or acrylics on it according to the occasion. As for maintenance, keep it away from water and high - temperature areas. Don't use excessive force when connecting or disconnecting sensors. If you have any questions, refer to the product wiki and other documents provided.
