The Waveshare's USB Type-A To UART converter module integrates the new version CH343G chip. The board supports a higher data rate (up to 6Mbps) and more serial port IO levels (5V / 3.3V / 2.5V / 1.8V) in comparison with CH340G. CH343 is a USB bus adapter chip, that realizes USB to a high-speed asynchronous serial port, and supports up to 115200bps communication Automatic identification and dynamic self-adaptation of baud rate, providing common MODEM contact signals for expanding asynchronous serial ports of computers, or feature USB bus for the common serial device or MCU.
Adopts 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)
Supports Mac, Linux, Android, Windows 7/8/8.1/10/11
Onboard resettable Fuse and Transient Voltage Suppressor, anti-overcurrent and anti-overvoltage, anti-surge, anti-static, improve shock resistance, stable and safe communication performance
Onboard IO protection circuits, anti-surge, anti-static, stable and safe communication performance
Onboard 3.3V and 5V TTL level switch pins for selecting TTL communication level
Support 3.3V/5V output (the module is powered by USB, and the onboard jumper should be shorted to 3.3V or 5V accordingly)
Adopts double-sided black immersion gold process, which is durable and has a good look
