This is a breakout board for TI’s DRV8824 microstepping bipolar stepper motor driver, a lower-current version of the DRV8825. It can 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), and it has larger current-sense resistors than the DRV8825 that allow for improved microstepping performance at low currents. This carrier has the same pinout, interface, and features as our DRV8825 carrier, which means it can serve as a direct substitute for the DRV8825 carrier when using lower-current stepper motors. This board ships with 0.1″ male header pins included but not soldered in.
