This is probably another really stupid question, but will it hurt a Nano if I run +5V to both the VIN pin and the 5+V pin?
The reason I ask is because I have a little sensor circuit that I would like to get a board made for and would like to have the option to use a Nano or Pro Mini, depending on what is handier / least expensive at the time. It is mostly pin compatible with either, with the exception of the VIN / RAW pin. Since, it is my understanding that, the RAW pin does not work with 5V, I need to run power to the VCC pin, which is in the same position as +5V pin on the Nano. It is no problem to tie two together and just leave the RAW pin out, if I use a Pro Mini, but I need both for the Nano, unless I can power it from an output pin, and I am just confusing myself.
