Hi,
Before searching the forum i thought teensy 3 ran on 3.3V, but now it seems that if connected to USB that the USB supplies 5V.
OK. Then i want to supply power from a computer power supply. I have found the answers to most of my questions already about USB and external power but just want confirmation before I do something I will regret.
I have the option of 3.3V or 5V from the power supply. I am leaning towards 5V because I need to put in a 1N5817 diode (which will use maybe .5V). But that will still mean around 4.5V for teensy 3.
So the question is when I power my teensy externally do I use the 5V or the 3.3V from my computer power supply? I am sure I have read somewhere that it is a little tolerant as to voltage.
Thanks.
