915 Generation Mini PCIE CH384L 4S DB-9 RS232 Serial Port Card

The following is the detailed introduction about our products:

The same chip can be configured as a four-channel serial port + parallel port/printing port or a four-channel serial port + extended multi-serial port of the PCI-E bus.
Provides a two-wire serial host interface, which can be connected to serial EEPROM devices like 24C0X to store non-volatile data.
The device identification (Vendor ID, Device ID, Class Code, etc.) of the PCIE board can be set in the EEPROM device.
3.3V power supply voltage, main I/O pins support 5V withstand voltage, and serial port low-power sleep mode.
