I am looking at the schematic of the SARA R3 R412.
I notice that the GPS TX/ and RX are connected to TP5 and TP6
GPS Enanble is connected to D26.
My question is, which DXX pins correspond to TP5 and TP6 ? Or are these not connected to any pins at all? What does it mean, TP?
My second question is, can you disable the GPS by pulling the D26 low, thereby achieving power saving?
