ESP32 open source handheld console

Overview

It is improved based on the odroid open source handheld machine, adding a type-c interface while retaining the microusb interface. At the same time, the "extremely advanced" headphone jack is retained. The serial port chip chooses the ch340 with a simpler peripheral circuit and a built-in crystal oscillator. It also adds a switching power supply to separately power the esp32 and a separate screen and SD card, making the system more stable while also Can save electricity
