M5Stack ATOM RS-232 M5Atomic TTL to RS232 LevelConverter Full-Duplex Communication Protocol Standa

Description:
ATOM RS-232 is a TTL-RS232 level-converter designed for use with the M5Atomic module. RS232 is a full-duplex communication protocol standard, which defines the electrical characteristics of the serial communication system. It is a widely used communication protocol in the field of industrial control. MAX232 chip is integrated in the module, which supports bidirectional conversion between TTL level and RS232 level. A DC/DC voltage regulator chip is integrated in the ATOM RS485, which can directly convert the 12V voltage of the RS232 hub to 5V to supply power for ATOM.
Features:
- Compatible ATOM Matrix/ATOM Lite - Built-in DC/DC - Full-duplex communication
Package Included:
- 1x ATOM RS-232 - 1x ATOM Lite - 1x Key - 1x M2*8mm Heagon socket cup head machine screw - 1x 18cm TYPE-C Cable
Applications:
- RS232 Communication - Industrial control node
