====== AVR 8-bit ======

When purchasing AVRs note...
  * The **-10xx** means 10MHz max speed, **-16xx** means 16MHz, etc.
  * However, the speed the chip can run at is proportional to the voltage, check the datasheet for the max speed at a given VCC (its near the end)
  * The **-nnPx** means DIP, **-nnAx** means TQFP and **-nnMx** means QFN
  * The **-nnxU** means RoHS, **-nnxI** is not RoHS
  * The **V** postfix means "Low voltage" generally 1.8V+
  * The **P** postfix is 'picopower' which is a different chip fabrication technology, thus Atmega168P is compatible with but slightly different than the Atmega168. P parts can run as low as 1.8V
