The ATOM STEPMOTOR is a stepper motor driver module suitable for Atom Lite only. There is a built-in DRV8825 driver chip, which can be used to drive a stepper motor. By adjusting the variable resistance, it provides a maximum driving current of 1.2A. The chip has its own over-current protection function, and a DIP switch on board that can adjust the step number flexibly. With a built in DC-DC, the external power supply can supply power to the ATOM, and the drive motor needs an external power supply (9-18V).
