hello
in a new revision of MKR series, would be possible create a simple way to insert a switch in the connection from the node of Q3a/Q3b and the node C8/U2?
would be the simpliest mode to disconnect the power to the "logic" part of the MKR and the accessory circuits connect to the 3,3v, manteining the possibility to charge the battery with the system off
an other way would be a circuitry like computers on/off pushbutton...
MKR series is a board oriented to the portable devices and this feature would be an interesting upgrade
