ATmega328 - TQFP

This is Atmel's high performance, low power 8-bit AVR ATMega328 microcontroller in a pint-sized TQFP package. Yes, [you really can solder that](http://www.sparkfun.com/commerce/tutorial_info.php?tutorials_id=96).

**Note:** There is no difference between this part and its previous version. This new copy was created to help make our in house assemblies easier to produce and manage.
