Description Atomic Stepmotor Base is a stepper motor driver base designed for the ATOM series. It integrates a DRV8825 driver chip and can drive stepper motors for compact motion-control projects. The base supports up to 1.2A driving current through variable resistor adjustment, includes overcurrent protection, and provides DIP switch control for flexible step subdivision settings. With its built-in DC-DC chip, the unit can be powered by an external 9V to 18V supply when driving a stepper motor.
