FTDI Serial TTL-232 USB Cable Shipping:4-6 Days SDA Level-shifted I²C data line:Just about all electronics use TTL serial for debugging, bootloading, programming, serial output, etc. But it's rare for a computer to have a serial port anymore. This is a USB to TTL serial cable, with a FTDI FT232RL usb serial chip embedded in the head. It has a 6 pin socket at the end with 5V power and ground, as well as RX, TX, RTS and CTS at 3V logic levels. These are perfect for use with a Boarduino, Meggy's, or other Arduino clones and
