EasyDriver Stepper Motor Driver

The Easy­Driv­er is a sim­ple to use step­per motor dri­ver that can dri­ver up to about 750mA per phase of a bi-polar step­per motor. Easy­Driv­er requires a 7V to 30V sup­ply to pow­er the motor and can pow­er any volt­age of step­per motor. The Easy­Driv­er has an on board volt­age reg­u­la­tor for the dig­i­tal inter­face that can be set to 5V or 3.3V. Con­nect a 4‑wire step­per motor and a micro­con­troller and you’ve got pre­ci­sion motor con­trol! Easy­Driv­er dri­ves bi-polar motors, and motors wired as bi-polar. I.e. 4,6, or 8 wire step­per motors.     It is a chop­per microstep­ping dri­ver based on the Alle­gro A3967 dri­ver chip, The microstep select (MS1 and MS2) pins of the A3967 are bro­ken out allow­ing adjust­ments to the microstep­ping res­o­lu­tion. The sleep and enable pins are also bro­ken out for fur­ther con­trol.FeaturesBased on the A3967 microstep­ping dri­verMS1 and MS2 pins bro­ken out to change microstep­ping res­o­lu­tion to full, half, quar­ter and eighth steps (defaults to eighth)Com­pat­i­ble with 4, 6, and 8 wire step­per motors of any volt­ageAdjustable cur­rent con­trol from 150mA/phase to 750mA/phasePow­er sup­ply range from 7V to 30V.
