Stepmotor Module+Fan module+Adapter

Description

STEPMOTOR is used for stepper motor control. It is perfect for any motion project as it can drive up to 3 Stepper motors with GRBL control.

It is built with MEGA328P has been flashed GRBL firmware. The module comunicates with M5Core via I2C(0x70)

Integrated 3 DRV8825, a simple but very powerful board that can control one bipolar stepper motor at the time and allows micro stepping up to 1/32 of a step.
