This stepper motor driver is powered by DRV8825. This driver has a same pin and interface as our A4988 stepper motor driver, so it can replace the A4988 driver. It is a high-powered stepper motor driver.

DRV8825 has adjustable current limits, over-current and over-heat protection, six micro resolution (down 1/32-step).

It uses 8.2-45V and can provide up to approximately 1.5 per phase without heat sink or forced air flow (rated up to 2.2 with adequate additional cooling per coil)

Specifications

1. With only simple step and direction control interface;

2. Six different step modes: full, half, 1/4, 1/8, 1/16, and 1/32;

3. Adjustable potentiometer can adjust the maximum current output, resulting in a higher step rate;

4. Automatic current decay mode detection / selection;

5. Overheat shutdown circuit, under voltage lockout, cross current protection;

6. Ground short circuit protection and load short circuit protection.
