Description:

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 (1MB pdf) 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 (see the Power Dissipation Considerations section below for more information). Here are some of the driver's key features:
Simple step and direction control interface
Can interface directly with 3.3 V and 5 V systems
Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout
Short-to-ground and shorted-load protection
4-layer, 2 oz copper PCB for improved heat dissipation
Exposed solderable ground pad below the driver IC on the bottom of the PCB
Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step
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
Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay)
45 V maximum supply voltage
Built-in regulator (no external logic voltage supply needed)
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)
We also carry a DRV8824 stepper motor driver carrier that can serve as a direct substitute for the DRV8825 carrier when using lower-current stepper motors. The DRV8824 can only deliver up to 0.75 A per coil without a heat sink (1.2 A max with proper cooling), but it has larger current-sense resistors that allow for better microstepping performance than the DRV8825 carrier at low currents. The only way to tell our DRV8824 carrier apart from the DRV8825 carrier is by the markings on the driver IC; if you have a mix of the two, you might consider marking them (there is a blank square on the bottom silkscreen you can use for this). For lower-voltage applications, consider our pin-compatible DRV8834 carrier, which works with motor supply voltages as low as 2.5 V.
This product ships with all surface-mount components—including the DRV8825 driver IC—installed as shown in the product picture.

Brief introduction
The DRV8825 stepper motor driver carrier board TI DRV8825 micro bipolar stepper motor drive is a breakthrough. The module has a pinout and interface with our A4988 stepper motor driver carrier is almost the same, so it can be used as a better performance of the pull-down menu board replacement in many applications. DRV8825 features an adjustable current limit, overcurrent and overtemperature protection, six micro-resolution (down 1/32-step). It uses 8.2 - 45 V, can provide up to about 1.5 per phase no heat sink or forced air flow (rated up to 2.2 per volume sufficient additional cooling).
