v3s_miniPC

Overview

Xiaobai completed the production of v3s_linux small computer, and it was very rewarding in the process. The Linux hardware part includes:
1. Onboard USB_hub, and the camera network card uses an external one, so sufficient USB interfaces are very important. 2. Use TFT_LCD display screen, the screen driver chip is ST7789.3, and use TC8002D power amplifier chip to drive the speaker (not implemented, the reason is unknown, and is still being investigated) 4. The serial port part uses CH340N, which has fewer pins and saves volume. 5. The power supply parts 3.3, 1.8, and 1.2 use sy8088aac DC-DC chip, which has a strong power supply and does not generate heat. 6. Add user LED and serial port indicators. 7. ADC button. 8. Use four-layer PCB.
