HPM5300EVK
==========

Overview
--------

The HPM5300EVK provides a series of interfaces for the characteristic peripherals of the HPM5300 series microcontrollers, including an ADC input SMA interface, a first-class motor control interface, an ABZ output interface, and an RS485/422 interface. HPM5300EVK also integrates one 2x20 pin IO expansion interface, which connects most of the IOs of the HPM5300 MCU for users to freely evaluate. HPM5300EVK expands NOR Flash storage for MCU and integrates an on-board debugger.
