The module uses a PL2303 chip and an easy-to-install driver. There are LED indicators on the module to show its working status: red for power, yellow for data sending, green for data receiving, which is convenient for system debugging. The baud rate of the module is 300bps-115.2kbps, and the RS485 transmission distance can be as far as 2km at the speed of 57.6kbps; The module can drive up to 32 RS485 devices, and the RS485 line is equipped with lightning protection, which effectively ensures the load capacity and working stability of the module.
