New definition of RD8G37Q48 core board

Overview

This is a newly defined RD8G37Q48 core board with all I/O pins exposed for easy functional verification. It features onboard buttons, a bunch of LEDs, and a power supply voltage selector (which can be adjusted via jumpers). The CH340 can be used to download and debug programs; enabling the RST pin allows for automatic program download via ISP.

The BOM is inaccurate; please refer to the schematic.

As usual, let's turn on an LED!

How to convert 5v to 3.6v
I need to convert the 5v power supply to 3.6v. I searched for a step-down IC but didn't find one. I only found one that is 3.3v. Now I use two 4007s in series and find that the voltage is 4.1v. The mi
