Stepper motor drivers for any 3D printer that makes use of the 4988 drivers. Used in the earlier Formbot printers for all stepper motor drivers, and for some of the modern Formbot stepper motor drivers.
The breakout board for the 4988 microstepping bipolar stepper motor driver features adjustable current limiting, over-current and over-temperature protection, and five different microstep resolutions (down to 1/16-step). It operates from 8 V to 35 V and can deliver up to approximately 1 A per phase without a heat sink or forced air flow (it is rated for 2 A per coil with sufficient additional cooling).
This board ships with male header pins soldered on and a heat sink already attached for high powered work.
