"What's the difference between all these Freedom boards?"
First, let's talk about the givens. All Freedom boards will have the following:

-Pin layout to accept any Arduino(R3) shield
-Multiple Power Options (USB, Battery or External)
-The Cortex-M0+ family excels at low-power operation!!
Now for the bells and whistles:
