Drive a 5-50V 4 wire (and 6 or 8 wire) bipolar stepper motors rated up to 6A using externally supplied 5V logic levels for controlling STEP and DIRECTION.
Control signal inputs are opto-isolated making it safe for CNC applications using a PC running suitable software (see User Manual below for details).
It can also be controlled using a microcontroller or simply two debounced switches connected to 5V.
Four pairs of MOSFETs are mounted back to back allowing you to add a heatsink of your choice if additional cooling is required.
