Mornsun Auxiliary Power Supply

Overview

This project uses the auxiliary power supply module based on Mornsun's URD480512YMD-10WR3, LCSC online store number (C6731983), with an input range of 18-75V (if such a wide input voltage range is not required, the URB series can be used instead, which will be much cheaper). It includes an onboard RT9013 to convert 5V to 3.3V.
Students participating in electrical engineering competitions can refer to this design to avoid the hassle of designing their own auxiliary power supply.
