[Lichuang Development Board] Tao's game expansion version

Overview

This nes game console is based on the GD32F470ZGT6 Liangshan School development board.
There are three versions of PCB diagrams in the design project. The first one imitates the official PCB design. It didn’t feel very good, so I drew a second version.

The third version of the PCB has been verified, has normal functions, and is designed in a handle shape for easy holding.
When I drew the schematic diagram, I forgot to connect the other three pins of the battery holder to ground, so some wires flew out on the back (now repaired).
The 5v charge and discharge module requires a separate board. If not, you can actually plug the power supply into Liangshan. Party to play. Click to turn on, press and hold for 2s to turn off. (Module link: https://oshwhub.com/li-chuang-kai-fa-ban/5v-chong-fang-yi-ti-dian-chi-mo-kuai)
If the font is displayed? ? ? ? , copy the font in the attachment to the SD card to repair it, and the SD card can also be copied for more gaming experience
