Hello from Spain,
I just got my navio+ from CGEO.IT install and nothing else can not connect to the MP and the I2C chip burns, burns nothing more touching.
Since Cgeo.it I have indicated here will help me.
I always aliminetado the whole ship Raspberry Pi 2 and from a PC via USB I also tested with a feeder 1A and 2A but nothing does the same.
This makes from the beginning not reached never work. and I followed the official manual.
I think that is also factory
Greetings and thanks to all
