IC has built in automatic half current functions to reduce the vibrations & current while motor is in static mode. The board required Step pulse and direction signal to operate the motor. Looks like a stepper motors drivers dream chip for the do it yourself. With a 5-phase motor, there are 10 steps per repeat in the stepping. You'll have to figure out the grey code required for the stepper motor to step. This board is default enabled since the enable pin has pull-up and you may short enable pin to GND to disable the board. 5-phase 5-wire stepper motor programming problem. All input signals can be feed through CN3. Micro-Stepping can be set with the help of jumper J1, J2, J3. Chopping frequency set to 83.3 KHz with the help of capacitor C5 100PF. PR1 trimmer potentiometer is provided to set the decay, 3.5V Slow Decay, 1.1V to 3.1V Mixed Decay, 0.8V-1V Fast Decay, and PR2 Trimmer Potentiometer provided to set the Current. It has multiple micro-stepping: Full step, 1/2th Step, 1/4th Step, 1/8th Step, 1/16th Step, 1/32th Step, 1/64th Step, 1/128th Step. 2 Phase stepping motor driver is a tiny board based on STK682-010 hybrid IC from ON semiconductor and it can deliver current up to 2.5Amp and has supply up to 32V DC.
