This Waveshare industrial USB to TTL converter uses an original CH343G chip, offering a high-speed asynchronous serial port connection, supporting up to 115200bps communication, automatic identification and dynamic self-adaptation of baud rate.
Housed in a robust plastic casing, the converter features protection in the form of an onboard resettable fuse and TVS Diode, providing over-current, over-voltage, reverse polarity and ESD Protection. An internal TTL voltage level switch also allows you to quickly switch between 3.3V or 5V.
Three LED Indicators allow easy identification of the operating status for debugging and general operation. Multiple popular systems are supported including Windows 7/8/8.1/10/11, Mac, Linux and Android.
