This is the SparkFun 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 compatible (like the Freeduino SB) boards. 3.3V version.
This big, bright red plastic enclosure, that we affectionately call "Big Red", will give your projects the protection (and attention) they deserve. It will also keep your electronics safe and sound indoors or outdoors as it includes a convenient weatherproof seal!
