The DRV8824 stepper motor driver carrier is a breakout board for TI’s DRV8824 microstepping bipolar stepper motor driver, a lower-current version of the DRV8825. The driver can only deliver up to 0.75 A per coil without a heat sink (it is rated for up to 1.2 A per coil with sufficient additional cooling), but it has larger current-sense resistors that allow for improved microstepping performance at low currents.
This carrier has the same pinout, interface, and features as the DRV8825 carrier, which means it can serve as a direct substitute for the DRV8825 carrier when using lower-current stepper motors (also a substitute for the A4988).
