Basic:bit IO expansion board is specially designed for micro:bit, which supports IIC communication. Although the shape is small, the function is very rich. It has an onboard 3.5mm audio interface, buzzer, programmable RGB lamp, a photoresistor, and many other electronic contrivances.
Moreover, it has expanded the micro:bit, all 20 pin headers, and 5 alligator clip interfaces. Users can combine the alligator clip and DuPont line with other sensor modules to complete some fascinating experiments. And this expansion board is designed with building block apertures, which is convenient for users to expand the building block shape, such as elevator tower, building block car, game controller and so on.
