C3001879_USB to serial port solution verification board based on CH340T chip

Overview

CH340N is a USB bus adapter chip that realizes USB to serial port. In serial port mode, CH340N provides commonly used MODEM communication signals, which are used to expand asynchronous serial ports for computers, or directly upgrade ordinary serial port devices to USB bus. Full-speed USB device interface, compatible with USB V2.0. Supports 5V power supply voltage and 3.3V power supply voltage, select the voltage by shorting the wiring cap.
