  • Hi there,
    Is there any manual on how to switch from 5V to 3.3V for a very basic user like me ? I don’t know what is the “trace” and where to cut, but have enough knowledge to solder the pad ;-)
    Also howto reverse it as i only need the 3.3v for setting up a GPS module then going back to 5V for arduino programing.
    Thanks.
