ROHM-STEPMO_EVK_202

Evaluation kit for micro step 36V stepper motor drivers BD63520AEFV IC based on Arduino/Genuino platform. As for its basic function, it is a low power consumption bipolar PWM constant current-drive driver with power supply rated voltage of 36V and rated output current (DC) of 2A. There are step modes of full step & half step, quarter step, sixteenth step mode by internal DAC (D-A converter) and for current decay mode, the ratio of fast decay & slow decay can be freely set so the optimum control conditions for every motor can be realized. In addition being able to drive with one system of power supply makes contribution to the set design’s getting easy. The purpose of the EVK is to allow the test and evaluation of the stepper driver IC in professional research and development environments.
