DRV8825 Stepper Motor Driver Module

The DRV8825 Stepper Motor Driver with Aluminum Heat Sink is a breakout board for TI’s DRV8825 micro stepping bipolar stepper motor driver.

The module has a pinout and interface that are nearly identical to those of the A498 Stepper Motor Driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications.

The DRV8825 features adjustable current limiting, overcurrent, and overtemperature protection, and six micro step 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). RoboticsBD

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) RoboticsBD
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. RoboticsBD
12. Exposed solder able ground pad below the driver IC on the bottom of the PCB
