The M5Stack ATOM RS485 DC/DC Voltage Converter Development Kit (SP3485EE) is a TTL-RS485 converter designed for use with M5Atomic. Its function is for TTL level and RS485 level conversion. RS485 is a communication protocol standard, which is used to define the electrical characteristics of drivers and receivers of a serial communication system.

It supports a multi-point system and is widely used in industry. When the application's equipment needs to communicate and be controlled through RS485, ATOM RS-485 is an excellent choice. A DC/DC voltage regulator chip is integrated into the ATOM RS-485, which can directly convert the 12V voltage of RS485 to 5V to supply power for M5ATOM, avoiding the trouble of using a separate power supply.
