In the Pin Out diagrams at " https://content.arduino.cc/assets/Pinout-NANOevery_latest.pdf ", the legends for the diagrams do not indicate what the ~ (tilde) means for D3, D5, D6, D9 and D10.
Also, why is "RESET" on 2 pins ?
Seems to me one pin was wasted that could have been something more useful ???
