The Stepper Board
Introduction
This board is based on the DRV8825 Stepper Motor Driver. It works with standard x4 wire bipolar stepper motors.
- Motor Voltage Supply from 8.2V to 45V
- Phase Current up to 2.5A, but ~1A is more realistic without a heatsink and fan
- Built in Step Controller, so strap the mode pins for the step mode: Full, Half, and Micro stepping.
- Easy control from a Microcontroller, digital pins to set the direction, enable the part, and step the motor.
- Fault Output Pin broken out and max current setting with a trim pot
Note that this board breaks out clamping diodes for each of the motor connections - these should not be needed, but I added them in for experimentation purposes.
