MegaPi Stepper Motor Driver


This module is designed to drive stepper motors. It uses the DRV8825 chip and has a maximum driving current of 2.5 A. DRV8825 is a complete micro-stepping motor driver, equipped with a built-in converter for easy operation. It is designed to drive bipolar stepper motors that work in full, 1/2, 1/4, 1/8/ 1/16, or 1/32 step modes. An on-board potentiometer is provided, which allows you to change the current of a motor easily.


  • Compatible with 4-wire bipolar stepper motors
  • Potentiometer, used to control the current of a stepper motor
  • On-board heat sink, facilitating heat dissipation
  • Capable of driving one-step stepper motors (green interface) • Color-coded male and female pins, ensuring correct connection • Small size, facilitating connection
