I am designing a PCB with an XEM3050 mounted on it. The board has an external connector for applying 5V power to the XEM3050’s J3 expansion connector. I would also like to connect a wire from the XEM3050’s P1 connector to my PCB so that I can use a switch to power the XEM3050 by either the DC jack (P1) or an external power supply. I would like to avoid connecting the two power signals together (in case they are both connected and powered).
Question: Does the XEM3050 have a jumper to disconnect P1 from the 5V net or does it have a trace that can easily be cut on the PCB from the bottom side?
