DRV8825 Stepper Motor Driver with Aluminum Heat Sink

The DRV8825 stepper motor driver carrier is a breakout board for TI’s DRV8825 micro-stepping bipolar stepper motor driver. The DRV8825 features adjustable current limiting, over-current and over-temperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 – 45 V and can deliver up to approximately 1.5 A per phase without a heat sink or forced air flow (rated for up to 2.2 A per coil with sufficient additional cooling).

This product is a carrier board or breakout board for TI’s DRV8825 stepper motor driver; we therefore recommend careful reading of the DRV8825 datasheet before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 2.2 A output current per coil.

Features:

1. Microstep resolutions: full, 1/2, 1/4, 1/8, 1/16, and 1/32.
2. Simple step and direction control interface.
3. Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step.
4. Adjustable current control lets you set the maximum current output with a potentiometer. Hence lets you use voltages above your stepper motor’s rated voltage to achieve higher step rates.
5. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay).
6. 45 V maximum supply voltage.
7. Built-in regulator (no external logic voltage supply needed).
8. Can interface directly with 3.3 V and 5 V systems.
9. Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout.
10. Short-to-ground and shorted-load protection.
11. 4-layer, 2 oz copper PCB for improved heat dissipation.
12. Exposed solderable ground pad below the driver IC on the bottom of the PCB.
