RS232 communication module CH340 U232 TVS protection serial line converter 


Features
Industrial-grade protection: TVS transient suppression protection, electrostatic ESD protection, surge protection, AB signal line short-circuit and power supply short-circuit protection (short circuit does not burn)
Transmission distance up to 1200 meters (tested at 9600bps)
Support baud rate 921600, much higher than 115200, use higher baud rate for paired mutual transmission
Multi-system support hot swap, support win98/CE/2000/2003/2008/XP/
WIN7/WIN8/WIN10/VISTA/LINUX/MAC OS X system, USB interface can be hot-swappable


Automatically discriminate and control the direction of data transmission, without any handshake signals (such as RTS, DTR, etc.), mode conversion can be achieved without jumper settings, ensuring compliance with existing communication software and interface hardware.


With TXD, RXD indicator
