USB to RS485 Serial Converter Module with CH340 Chip

HIC UR4 USB to RS485/RS232 Converter module is designed to achieve the inter-conversion between USB and RS485/RS232 serial port bus.. When plug in that converter module into USB port, it can simulate standard serial port in the PC. It is compatible with the serial port programs in Window system. And multiple protection circuits have been added to ensure its signal transmission integrity and EMC performance in designing that serial port conversion module. Thus, it can be applied in various type of industrial application. Small size, low cost, refined simple design, high reliability, it is an ideal serial port conversion module.
