Sparkfun Red Board

Sparkfun Red Board

The Sparkfun RedBoard is a meld of features from different Arduino boards past and present. It has the FTDI chip, which is more stable than the kludged ATmega16U2 USB to serial converter of the Uno. At least I've never bricked an FTDI chip. It has the R3 pinout of the latest Uno, so newer shields can be used with it. Finally, it uses the smaller, simpler, Optiboot loader. Sparkfun thinks this is the best of all possible worlds. They could be right.
