USB3.X test board

Overview

esp32-c3
voltage conversion chip SPX3819M5-L-3-3/TR;

voltage test resistor voltage division, port io4,
current test with INA199A1DCKR, port io0,
i2c port: sda is io7, scl is io6,
usb voltage, 3.3v voltage, ground lead.

Note:
voltage measurement voltage division is at least 10:1
due to component accuracy, data must be corrected when writing the program,
