What is FT232R USB UART Driver?

FT232R USB UART Driver is a software program used to communicate and transfer data between a computer and USB devices that use UART (Universal Asynchronous Receiver/Transmitter) technology. It is a USB to UART interface designed and manufactured by Future Technology Devices International (FTDI).

The driver enables the computer to recognize and communicate with the USB device, allowing users to transfer data, update firmware, and perform other tasks. The FT232R USB UART Driver is often used in microcontroller programming, Arduino projects, and other electronics applications. It is compatible with Windows, Linux, and Mac operating systems. The driver can be downloaded from the FTDI website or found in software packages that use it.


The FT232R USB UART IC is a USB-to-serial converter chip that allows a computer to communicate with devices that use serial communication protocols.
