Waveshare Micro USB to UART High Speed ​​Bandwidth Transmission Module Connectors, Micro USB

Functionality
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. On-board resettable fuse and transient voltage suppressor, anti-overload and anti-overvolt, anti-surge, anti-static, shock enhancement, stable and safe communication performance
4. On-board IO protection circuits, anti-surge, anti-static, stable and safe communication performance
5. Onboard 3.3V and 5V TTL level pins for TTL communication level selection
6. Support 3.3V/5V Output (The module is powered by USB and the on-board jumper should be shorted to 3.3V or 5V accordingly)
7. Adopt double-sided black dipping gold process, which is durable and has beautiful appearance
Description of the indicator
1. PWR: Power indicator, turn on when voltage is detected by USB interface
2. RXD: receiving indicator, light up when data is sent from the device interface
3. TXD: Send indicator, light when data is sent from USB
Definition of nitpickers
1. VCC: 5V or 3.3V output for external device (configured by Jumper)
