M5Stack GRBL Module 13.2 Stepmotor Driver (DRV8825)

Drive up to three bipolar stepper motors simultaneously with this three-axis stepper motor driver module, stackable with other M5Stack modules. It uses an ATmega328P-AU controller with three sets of DRV8825PWPR stepper motor driver chips, so it can drive three bipolar steppers at the same time. This module uses I2C to communicate with other M5Stack modules and integrated DIP switches to adjust motor step subdivision (maximum support of 1/32 step subdivision) and I2C address adjustment (the default address is 0x70 but you can change it to 0x71). You can achieve six-axis control by stacking two GRBL 13.2 modules together! The power input interface is DC/9-24V, the motor drive current can reach 1.5A, and three sets of limit switch signal interfaces are open so you can connect an external limit switch to reverse the motors. Suitable for many different stepper motor uses such as 3D printers, robotics, etc. Features
