M5Stack Stepper Motor Driver Board For Arduino ESP32 GRBL 12C Step-Motor MEGA328P
This module contains a MEGA328P, which is equivalent to U N O.
Using the modified GRBL library (open source).
Using I2C commnuicate with the main core, GCODE can be sent to GRBL through I2C.
The default I2C address is 0x70. One core can connect to multiple STEPMOTOR modules, users need to modify the address to compile.
Witch high-quality DRV8825 module, peak current up to 1.5A.
