Description: This is a breakout board for the standard TQFP-44 package.
All pins of the TQFP are broken out to a 44 pin 0.1" pitch header. The two rows of DIP pins are spaced 0.6" apart so they fit nicely into a breadboard.
BTW, this is the same package size as the ATmega32U4 chip that is used on the new Arduino Leonardo.
