Changing the VID/PID allows you to hide the device from the standard VCP driver and use FTDI’s D2XX direct driver for lower latency applications. ft323r usb uart

The FT323R is a highly integrated USB-to-Asynchronous Serial Data Transfer (UART) IC designed by FTDI Chip. It is the spiritual and technical successor to the iconic FT232R, addressing modern low-power and low-voltage requirements while retaining full driver compatibility. The "R" in its name signifies an integrated and integrated clock (no external crystal required), making it a complete System-on-Chip (SoC) for USB-serial conversion. | Feature | FT323R | CP2102N (Silicon Labs)

For the maker community, the "FTDI Breakout Board"—a small circuit board breaking out the FT232R pins—has become an essential tool. It democratized embedded development by removing the need for expensive specialized programmers. Its "plug-and-play" nature means that a hobbyist can interface a 3.3V or 5V logic circuit with a computer in seconds, without worrying about complex driver development or signal translation. The "R" in its name signifies an integrated

FT323R due to driver stability and EEPROM flexibility.
