Product Description

The 5 foot Serial UART USB to 3.3v TTL PIN Header Cable (TTL level) adapter allows you to connect your computer through the USB port and use it as a regular serial communication device with support for 7 or 8 data bits. All USB protocol is handled within this adapter using an FTDI Chip set. There is no other device or programming required.

The USB to 3.3v TTL PIN Header Adapter Cable is perfect for embedded systems that require a serial connection to a computer and provides a USB to TTL Serial interface to 6-pin header. The board attaches directly to the USB bus via a standard type A receptacle connector. It shows up on any Windows computer as a standard serial COM port. Any applications that talk to this COM port is automatically converted to USB and back to UART on your target board.

Worked perfectly for running an update on an ESP8266 that I had. The wires don't seem to be so flimsy they will break in my bag and online documentation is good.

Works perfectly in Windows 10. I attached the Vantage Pro2 and it communicates perfectly. Remember to connect TX to RX and RX to TX and short the CTS to RTS - Brown to Green. The command to wake the console up is \n. Baud rate 19200. Type TEST and enter and it should return TEST. LAMPS 1 - turns the console lamp on, LAMPS 0 - off (via Hyperterm).
