About This Product

The FTDI TTL-232R-3V3 is a USB-to-UART serial converter cable designed for equipment that communicates using 3.3V TTL-level UART signals. The conversion electronics are integrated into the USB connector, while the opposite end provides a 6-pin interface for connecting to compatible embedded systems, development boards and serial devices.
