When I look at the circuit board traces
on the back on the BOE it looks to me that both the 9 volt battery and the
wall wort power supply are connected to the same line which is fed into the
voltage regulator on the BOE. Why shoud a battery power the regulator any
differently than the Wall wort?
I am also doing the experiments in WAMC student book.
