Waveshare PL2303 USB To UART (TTL) Communication Module V2, USB-A Connector

This is the PL2303 USB UART converter Board. This is a great little tool for embedded systems that require a serial connection to a computer. The board can simply attach to a USB-C bus and will appear as a standard COM port

Pinout:

1. VCCIO ↔ 3.3V or 5V output (the module is powered from USB, and the onboard jumper should be shorted to 3.3V or 5V)
2. GND ↔ GND
3. TXD ↔ MCU.RX (signal direction: MCU.RX << PL2303 << PC.TX)
4. RXD ↔ MCU.TX (signal direction: MCU.TX >> PL2303 >> PC.RX)

Features: 

1. Adopts PL2303GS new version device
2. Supports windows XP/7/8/10/11/…

3. 3x VCCIO power mode via jumper setting:

   1. VCCIO – 5V: 5V output
   2. VCCIO – 3.3V: 3.3V output
   3. open the jumper: powered from target board (1.8V/2.5V/3.3V/5V)
4. 3x LED indicators: TXD, RXD, PWR

Package Includes:

1 x PL2303 USB UART Board (type A) V2
1 x 4-pin custom connector jumper wire x1
