USB Mod 3 (FTDI FT232BM)

The USB Mod 3 (FTDI FT232BM) shown in Diagram 1 is a second-generation, low-cost integrated module for transferring serial data over USB. Based on the FTDI FT232BM USB UART IC, the USBMOD3 can transfer rates of up to 1000k baud (RS232) and 3000k baud (RS422 / RS485). The USBMOD3 offers a complete plug-and-play solution making it ideal for rapid prototyping and development.
