This is really cool. One cautionary thing though. I think that because of breadboard capacitance if you try any sort of high frequency stuff on the breadboard (like >= 10MHz) you'll get all sorts of weird effects. (This is just a breadboard problem that occurs at high frequencies, not an ARM problem).

I'm just an amateur in this area, so if someone who is more knowledgeable could confirm or deny with I wrote above that would be great.

1. Others estimate higher max frequency. This one's on the high side of estimates:

2. See also this video (and comments on video) where they measure:
