AC164128接口板主要用于电源管理和电机控制。This PICtail MC board interfaces with Explorer 16 (DM240001) and the HV/LV Power Module (DM300021 and DM300022). It has a variety of test points that will make debugging of your application easier. It also has hardware support for sensor and sensor-less applications such as Hall sensors, optical encoder, back EMF and current sensing.This uses dsPIC33F device family for the MC development as opposed to the DM300020 that targets dsPIC30F for the MC application development.
