Sorry this seems like a simple question, but just can't seem to find the answer any where


When using the MKR zero and a lipo battery how do you turn it on/off ?

Is the a way to do through the board, is it just a simple case cutting the positive cable and putting a switch in


Any Help would be great appreciated

A switch is the simplest.

Or you could use the sleep / standby functions just to lower the power usage.
AFAIK none of the Arduino boards have a dedicated ON/OFF switch.

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.

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
