Keyestudio 3V Sensor Shield Board For BBC Micro:bit

The Keyestudio 3V Sensor Shield Board is an expansion board for the BBC micro:bit. With the micro:bit plugged into its edge connector, the IO pins are brought out to 3-pin G/V/S headers, so sensors and modules connect with simple Dupont cables instead of crocodile clips. It is ideal for classrooms and makers who want to connect more parts to a micro:bit.
