Secondary power input for Rock64 through pi2 Bus

[nmhart322]

those pins are not 5VDC IN they are 5V source to power components from the rock64.  to use them to supply power to the board is risky. get a copy of the schematic and look at the actual input power supply line and compare it to the 5v header circuit. if you want a solid 5v DC IN the remove the barrel jack connector from the board and  hard wire  the line from your power supply.

Thank you. I will try this.
