this evaluation board is a board for driving the stepping motor with a rohm's stepping motor driver bd63715aefv. motor drive and driver the motor can be driven by vcc for power supply and 5v power supply for control signal. drive / stop and excitation modes can be set with an external switch. the input interface adopts the clk-in drive system, and the excitation mode supports full step, half step, quater step, 1/8 step, and 1/16 step mode by the built-in dac.
