That's very cool.

I've been using Teensys since 3.0.  In fact, I ran some clock 
performance tests on 5 teensy 3.1s - nothing unusual found.


I like the teensys because they have decent ADC (16 bit differential) 
and DAC (not PWM DAC), so you can actually do some interesting audio 
frequency stuff (like using them as a doppler radar processor to detect 
heartbeats).



I'm glad they're still pushing the envelope.
