Monolithic Power Systems (MPS) EV6500A Evaluation Board

Monolithic Power Systems (MPS) EV6500A Evaluation Board is designed to demonstrate the capabilities of the MP6500A, a stepper motor driver with a built-in micro-stepping translator. The MP6500A functions from up to 35V supply voltage and delivers up to 2.5A motor current. This EV6500A board features a bipolar stepper motor in full-, half-, quarter-, and eighth-step modes by setting the MS2 and MS1 pins. The EV6500A evaluation board is available in a QFN-24 (5mm x 5mm) package.
