Feature:Note: The FT232BL is made in China version, but function is same as original one.Driver Link: http://www.ftdichip.com/Drivers/VCP.htm FTDI based USB to TTL Serial Cable are designed using the the standard FT232RL chipset. The cables provide a fast, simple way to connect devices with a TTL level serial interface to USB. RX and TX LEDs indicator The cables are available with a 6-way SIL, 0.1" connector TTL levels is 5V The TTL-232R cables are a family of USB to TTL serial UART converter cables incorporating FTD's FT232RQ USB to Serial UART interface IC device which handles all the USB signalling and protocols. The cables provide a fast, simple way to connect devices with a TTL level serial interface to USB Each TTL-232R cable contains a small internal electronic circuit board, utilising the FT232R, which is encapsulated into the USB connector end of the cable. The other end of the cable comes with a selection of different connectors supporting various applications. Cables are FCC, CE, RoHS compliant and are available at TTL levels 5V. Cables are available with a 6-way SIL,0.1¡±pitch connector The USB side of the cable is USB powered and USB 2.0 full speed compatible. Each cable is 0m long and supports a data transfer rate up to 3 MbaudWiring： 1 - Black:GND Ground 2 - Blue:CTS Clear to Send Control/Handshake Signal 3 - Red: VCC +5V 4 - Green:TXD Transmit Asynchronous Data 5 - White:RXD Receive Asynchronous Data 6 - Yellow:RTS Resquest to Send Control/Handshake Signal Package include: 1X 1 x USB to TTL Serial Cable
