The M5Stack Stepmotor Module is designed for stepper motor control, capable of driving up to 3 stepper motors with GRBL firmware. Built around the MEGA328P microcontroller (pre-flashed with GRBL), it communicates with M5Stack Core via I2C (address 0x70).

Integrated with 3× DRV8825 stepper drivers, each channel supports micro-stepping up to 1/32 of a step for precise motion control.

Key Features

• 3-Channel Stepper Control – Independent X, Y, and Z axis outputs
• DRV8825 Drivers – Up to 1/32 micro-stepping per channel
• GRBL Firmware – Pre-flashed MEGA328P for G-code control
• I2C Interface – Communicates with M5Stack Core at address 0x70
• 9–24V Power Input – Wide voltage range for various motor types
