Overview

This product is a carrier board or breakout board for TI’s DRV8824 stepper motor driver; we therefore recommend careful reading of the DRV8824 datasheet (1MB pdf) before using this product. This stepper motor driver lets you control one bipolar stepper motor at up to 1.2 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
  • 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)
  • 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
  • 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 DRV8825 stepper motor driver carrier that can serve as a direct, higher-power substitute for the DRV8824 carrier. The DRV8825 can deliver up to 1.5 A per coil without a heat sink (2.2 A max with sufficient additional cooling). 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 DRV8824 driver IC—installed as shown in the product picture.
