DRV8825 stepper motor driver based on TI DRV8825 chip.
Works with stepper motors with voltage from 8.2 to 45V and current up to 1.5A per phase (up to 2.2A with forced air cooling). Allows you to adjust the output current, has overload and overheating protection, six microstep options: full step, half step, 1/4, 1/8, 1/16 and 1/32 steps. It can work with both 3.3 and 5V logic.
It is pinned identical to the A4988, but the DRV8825 stepper driver board has a trimmer on the other side of the PCB, so be careful with the correct stepper driver board orientation!
