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.
