This kit contains everything you need to build your very own Uno-Compatible development board! Simply follow the Assembly Guide and after some basic soldering, you'll have made a fully-functional Arduino-compatible board (in fashionable SparkFun Red). The included ATmega328 comes pre-loaded with the Arduino "Optiboot" bootloader so you don't have to worry about loading the firmware, simply solder it together, connect an FTDI Basic and load your favorite Arduino sketch!
