RS485 to TTL 3.3V 5V Converter UART to RS485 Module

Description

HIC TTL485M 5V 3.3V TTL to RS485 Converter UART to RS485 converter module can be RS485 and TTL 3.3V 5V port inter-conversion. That UART converter module has automatic stream controlling function to realize RS485 receiving and transmission automatic conversion.  It enables user to use it like that using a RS232 serial port without considering the direction and makes user to do program easily. Its conversion speed is 500kps automatic. When design the ttl rs485 circuit module, designer has added multiple protection circuits to ensure it's signal integration and high EMC performance in signal transmission process.  It is easy to use, refined external shape, simple design, low cost and high reliability and can be applied in various fields in industrial site.
