RS232 Module 13.2 with DB9 Male Connector _RPI_POWER_HAT and a power regulator toThe RS232M Module 13. 2 is an expansion module of RS232 serial communication with isolation, using the scheme of TD301D232H serial port conversion chip and male DB9 interface to enable the interface conversion between RS232 and TTL CMOS logic level signals, and using the F0505S 2WR3 DC DC power module to enable electrical and noise isolation functions, toggle switch and coding switch. It enables the pass through or cross switching of DB9 signal lines,
