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