Hi! I'm bought HiFiberry Digi+ w transformer to build the network player based on RPi 2b. First off all i want to use linear PSU that will be connected to P3 of my Digi+. As I understood there is no need additional actions for that - i need only to solder wires or PCB mount connector to P3? I want also to add a simple 1602 LCD screen, can I take the power for it from Digi+ GPIO?
PSU is DIY (Thoroidal transformer 30VA/ 2x7V +Double DC LT1083 20V 7.5A)
