M5Stack ATOM Tail485 - RS485 Converter for ATOM

The Tail485 is a RS485 converter designed for ATOM, which is used for converting RS485 signals to TTL. RS485 is a standard defining of the electrical characteristics of drivers and receivers for use in serial communications systems, widely used in the industrial field. It facilitates long distance communication in electrically noisy environments. Multipoint systems are supported. When the project equipment needs to communicate and control through RS485, it is a good choice to use the Tail485 for interface type switching. A DC/ DC voltage regulator chip is integrated in the tail485 module, which can directly convert the 12V voltage of the RS485 to 5V to supply power for USB type C interface, avoiding the inconvenience of a separate power supply.
