This module is blue PCB now,please know it .
The DRV8825 stepper motor driver carrier is a breakout board for TI's DRV8825 microstepping bipolar stepper motor driver. The module has a pinout and interface that are nearly identical to those of our A4988 stepper motor driver board, 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 microstep resolutions (down to 1/32-step). It operates from 8.2 â€“ 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).
1ďĽ‰Simple step and direction control interface
2ďĽ‰Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
3ďĽ‰Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates
4ďĽ‰45 V maximum supply voltage
5ďĽ‰Built-in regulator (no external logic voltage supply needed)
6ďĽ‰Can interface directly with 3.3 V and 5 V systems
7ďĽ‰Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
8ďĽ‰Short-to-ground and shorted-load protection
9ďĽ‰4-layer, 2 oz copper PCB for improved heat dissipation
10ďĽ‰Exposed solderable ground pad below the driver IC on the bottom of the PCB
11ďĽ‰Module size, pinout, and interface match those of our A4988 stepper motor driver carriers in most respects (see the bottom of this page for more information)
