I am using a PI 3 model B+ with and Sparkfun explorer USB module to connect a XBee-PRO S2C 2.4GHz transceiver with a 2.5A power supply. I now want to connect the standard Raspberry 7 inch display to the PI, but the first 26 pins are used by a GPS expansion board. How should I connect this display and will the one power supply be sufficient?
I noticed that the display also has a USB power socket. Should or can I connect that with a separate power supply (with I don't prefer) and insert the data cable in the PI. Or is there an other way to interconnect those apart from the power pins used by the expansion board?
