Product Description

The DRV8825 microstepping bipolar stepper motor control has adjustable current limiting, overload, temperature protection and six microstep resolutions (up to 1/32 steps). It operates from 8.2 V to 45 V and can deliver up to approximately 1.5 A per phase without heat sink or forced air flow (suitable for a maximum of 2.2 A per coil with sufficient additional cooling). The driver has a pin-out and interface that is almost identical to that of our A4988 microstep driver drivers, so that it can be used as a replacement drop-in for those boards in many applications.

- Easy interface
- Six different step resolutions: full step, half step, 1/4 step, 1/8 step, 1/16 step and 1/32 step
- With the adjustable current control you can set the maximum current output with a potentiometer, with which you can use voltages above the nominal voltage of your stepper motor to achieve higher step speeds
- Intelligent heel control that automatically selects the correct flow decay mode (fast decay or slow decay)
- 45 V maximum supply voltage
- Built-in controller (no external logic supply voltage required)
- Can be connected directly to 3.3 V and 5 V systems
- Thermal switch-off at too high a temperature, over current switch-off and underload blocking
- Short circuit protection
- 4-layer, 2 oz copper circuit board for improved heat dissipation
