FTDI USB to TTL Serial Cable

 

FTDI CableAVIT Research FTDI based USB to TTL Serial Cable are designed using the de facto standard FT232RQ chipset.  The cables provide a fast, simple way to connect devices with a TTL level serial interface to USB.

The cables are available with a 6-way SIL, 0.1" connector and are available at TTL levels of +5v and +3v3 in BLACK or TRANSPARENT with Rx and Tx LEDs.

 

  • Simple and Easy way to give USB support to your designs

  • Connects directly to microcontroller UART or I/O pins

  • PC communicates as a standard serial device

  • All circuitry integrated into sleek, moulded USB plug

  • Compatible with legacy software.

  • Based on FTDI FT232R

  • 6-way connector (Gnd, CTS, VCC, TX, RX, and RTS)

  • Supports data rates up to 3 Mbaud allowing a significant performance increase over a standard serial port.

  • Allows devices to be powered from the USB port.

  • All I/O are protected from shorts and ESD.

  • Drivers Supplied by FTDI

  • Can by customised for own branding (USB VID, PID, Descriptors etc.)

  • Cable Length 1.80m (6 ft)
