How do I switch over to the 12 volt power supply? The Board Features Overview page says the 5 and 12 volt circuits can be accessed from pin D22, but I am having trouble finding that pin. I notice there are some pins labeled Sw3, Sw5, and Sw12 at the bottom of the 20-pin headers. Is that where I switch the supply voltage, and if so, which pins am I connecting? I am also a little confused on how the jumper pins that sit at the head of the grove terminals work. Do I need to move the jumper pin for the grove terminal I plug into if I switch the power supply? Thanks!
