Reference Design / Application Evaluation Kit
-
- Evaluation Board - BD63725BEFV-EVK-001
This evaluation board is a board for driving the stepping motor with a ROHM's stepping motor driver BD63725BEFV. 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.
