DRV8825 Stepper Motor Driver Controller for StepStick 3D Printer

This module can drive one stepper motor. Use this board to control your stepper motor from your microcntroller, Arduino, RaspberryPi, etc. It uses the hugely popular Texas Instruments DRV8825 IC. The stepper motor can be controlled through just 2 pins - one for direction and the other for speed and step control. This makes it easy to control the speed and position of the motor from a microcontroller, Arduino, Raspberry Pi, etc.

It offers numerous features like features adjustable current limiting, over-current and over-temperature protection, and six different microstep resolutions (down to 1/32-step). It can drive stepper motors with an input voltage of 8V to 45V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (it is rated for 2.2 A per coil with sufficient additional cooling).
