MegaPi Stepper Motor Driver

Description:

This module is designed to drive stepper motors. It uses DRV8825 chip and has a maximum driving current of 2.5A. The DRV8825 is a complete micro-stepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full, 1/2, 1/4, 1/8/ 1/16, or 1/32 step modes. We add an on-board potentiometer, so you can change the current of motor easily.

Features:

• Compatible with 4 wire bi-polar stepper motors;

• A potentiometer to control the current of the stepper motor;

• Capable of driving one stepper motor (green interface);

• Color-code male and female pins ensure connecting with MegaPi correctly;

• Small size for easy connecting with MegaPi.
