ROHM - BD63525AEFV-EVK-001

The ROHM evaluation board is used for driving the stepping motor with ROHM's stepping motor driver BD63511EFV. The motor can be driven by VCC for power supply and 5V power supply for control signal. The 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.
