Is it possible to power Teensy 3.* directly from 2 AA batteries, bypassing the regulator (assuming that USB isn't needed)? It looks like the chip is rated to run down to 1.7V, but I've seen it suggested in the forum that a boost regulator would be necessary. Thanks!
 
Sure, it's possible. I don't think you even need to bypass the regulator because it will get bypassed automatically when the voltage drops below something it can usefully regulate. A boost regulator might help you squeeze more juice out of the batteries.
