Description

The FTDIFuture Technology Devices International FT232R ICIntegrated Circuit is a USB Serial Adapter that converts USB signals to 2-wire UARTUniversal Asynchronous Receiver-Transmitter (TXTransmit, RXReceive) for 1.8V to 5V systems. It operates at USB Full Speed and supports baud rates from 300bps to 3Mbps.

This adapter should auto install on most operating systems without the need for additional drivers.

The FT232R IC has power pins (VCC, GND), data pins (TX, RX), control pins (RI, DTR, DSR, DCD, RTS, CTR), and CBUS GPIOGeneral Purpose Input Output pins (CBUS0-CBUS4), defined in the table below. However, some modules may not include some or all of the control pins or CBUS pins.
