FT232 is a USB to TTL Serial converter IC used in applications where USART devices need to communicate to external devices through USB. This IC is compatible with USB 2.0 speed and standards. In fact this Chip was used in earlier versions of Arduino such as NG, Diecimila and Duemilanove to provide communication from Controller to PC through USB.

The FT232 schematic is a popular circuit board layout design for microcontroller circuits. It’s commonly used to create serial ports because it has the ability to handle high voltages and currents. This makes it perfect for connecting devices like modems, printers, network adapters, and more.
