Module13.2 GRBL is a three-axis stepper motor driver module in the M5Stack stackable module series. It uses the ATmega328P-AU controller with three DRV8825PWPR stepper motor driver chips, enabling simultaneous control of three bipolar stepper motors.
The module provides an I2C communication interface and integrates a DIP switch for motor step subdivision adjustment, up to 1/32 microstepping, and I2C address configuration. It supports dual I2C addresses 0x70 and 0x71, allowing two Module13.2 GRBL modules to be stacked for six-axis control.
The power input interface supports DC 9-24V, and each motor driver channel supports up to 1.5A drive current. It also includes three sets of limit switch signal interfaces for external limit switches, using active-low motor braking control.
