Hello,
This might be a very obvious and simple question, but I haven't been able to find the answer via searching.
Teensy++ 2.0 runs on 5v by default. There's a way to convert it to 3.3v, so it draws less power. If I do that, will the 5v pin become a 3v pin or will it only affect the operating frequency of the processor itself?
More specifically, I have a PS/2 keyboard running with Teensy++ 2.0, which requires 5v. Will I be able to power it from Teensy's 5v pin or will the power drop down to 3v and I won't be able to use it?
Thanks.
