M5stack RS232 Module 13.2 with DB9 Male Connector

Description

M5Stack RS232M Module 13.2 is an isolated RS232 serial communication expansion module with a DB9 male interface for M5Stack host projects. The M5Stack RS232M Module uses a TD301D232H serial port conversion chip to convert between RS232 and TTL/CMOS logic level signals, while the F0505S-2WR3 DC/DC power module provides electrical and noise isolation. It is built for industrial automation, instrumentation, medical equipment and communication equipment that need reliable full-duplex serial communication.

Note: This isolated RS232 module supports communication speeds up to 115200bps, uses a DB9 male interface, and provides a 9-24V DC power input socket with a corresponding DC-DC circuit. The toggle switch and encoder switch allow straight-through or crossover DB9 signal-line switching and serial interface switching for different connection requirements.
