Hi everyone!
I'm new to the game: longtime Arduino user, just discovered these Teensy gems!
I have a project where everything is running at 3.3V (power, signals, etc.) and I already have a 3.3V regulator to power everything.
The Teensy 3.2 I'll use won't have to directly power anything.
I know that the Teensy is usually powered by USB (regulated 5V) or unregulated external power source.
I'm wondering if I could power the Teensy 3.2 directly off my 3.3V regulator, to simplify the design (no need for a 3.3V->5V stepup) and hopefully save power (battery-operated device).
This, of course, after having uploaded my sketch via USB; I won't need USB anymore after that.
Thank you very much for any hint!
Fernando
