Micro:bit Driver Expansion Board ECG Sensor Built in 512KB of SRAMDescription Since the advent of micro: bit, its simple and practical way of programming is widely loved by makers, students and teachers. Its sample design, coupled with a wealth of pin resources, give it infinite possibilities. This expansion board not only leads to 9 micro: bit onboard GPIO interfaces, but also comes with 4 way motor drives and 8 servo interfaces, of which 4 way motor drives can be reused as 2 way stepper motor drives.
