Waveshare Type-C / USB-C to UART High Band Rate Transmission Module Connectors

Description

Features
1. Adopt new version CH343G chip. Compared with CH340G, it supports higher data rate (up to 6Mbps) and more serial port IO levels (5V / 3.3V / 2.5V / 1.8V)
2. Support Mac, Linux, Android, Windows 7/8/8.1/10/11
3. Onboard resettable Fuse and Transient Voltage Suppressor, anti-overcurrent and anti-overvoltage, anti-surge, anti-static, improve shock resistance, stable and safe communication performance
4. Onboard IO protection circuits, anti-surge, anti-static, stable and safe communication performance
5. Onboard 3.3V and 5V TTL level switch pins for selecting TTL communication level
6. Support 3.3V/5V output (the module is powered by USB, and the onboard jumper should be shorted to 3.3V or 5V accordingly)
7. Adopt double-sided black immersion gold process, which is durable and has a good look

Indictor Description
1. PWR: Power indicator, turn on when the voltage is detected from USB interface
2. RXD: Receiving indicator, turn on when data is sent back from the device interface
3. TXD: Sending indicator, turn on when data is sent from USB

Pinouts Definition
1. VCC: 5V or 3.3V output for external device (configured by jumper)
2. GND: Ground
3. TXD: Connects to MCU.RXD
4. RXD: Connects to MCU.TXD
5. RTS: Connects to MCU.CTS
6. CTS: Connects to MCU.RTS
