Stepper motor drivers for any 3D printer that makes use of the 8825 drivers. Used in the newer Formbot printers for some of the stepper motors, traditionally the Y axis.
The breakout board for 8825 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and six microstep resolutions (down to 1/32-step). It operates from 8.2 V to 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). The driver has a pinout and interface that are nearly identical to those of the 4988 stepper motor driver carriers, so it can be used as a higher-performance drop-in replacement for those boards in many applications, but firmware will have to be modified or updated.
This board ships with male header pins soldered on and a heat sink included but not attached.
