Features:

• This is a basic breakout board for the FTDI FT232RL USB to serial IC.
• The pinout of this board matches the FTDI cable to work with official Arduino and cloned 3.3V Arduino boards.
• It can also be used for general serial applications.
• The DTR pin allows an Arduino target to auto-reset when a new Sketch is downloaded.
• The pins labeled BLK and GRN correspond to the colored wires on the FTDI cable.
• The black wire on the FTDI cable is GND, green is DTR. Use these BLK and GRN pins to align the FTDI basic board with your Arduino target.
