Hi there! Could anyone help me with Linear PSU upgrade for Digi+ ? Looks like I've screwed up with polarity and killed my RPi 2. I've tough that Power contact on P3 is nearest to GPIO, am I wrong? If not, then I did something wrong with PSU. I've built it with linear PSU module Double DC LT1083 20v, 7.5a and toroidal transformer 30 VA, 2x 7V. Now when I turning power on lights are OK on both boards but nothing happens. Ethernet and HDMI ports are dead. Hope Digi+ is alive.
