here is an unusual question. I have NOT found ANYTHING answering my question which is why I'm here.
My question is this: I am about to make a server cabinet for 4 Raspberry PI's it USED TO BE the 2 modB... That is until I learned about the new Pi 3 on the 29th of February. One PI is for hosting a Web server, one for an email server, and the other two for either support, or various other projects as to not slow down the Web and email servers. Everything in the cabinet is designed to be minimalist. The switch I plan on using is a 4 way micro switch for ethernet connection to the network.
Here's what I am wondering. I want to Daisy chain at least 2 of them together using one power source... So, the 1st Pi would be plugged into the primary power source of 5.1V 2.5A... BUT the second PI, I want to use the 5V and GND GPIO posts on the first PI to micro USB power input on the second PI. Is this possible? How well would it work? How would I go about making the secondary power source meet 2.5A (if I need to) as to not fry the second PI?
ANY info yall can give me about whether or not this is possible and how to make it happen would be great!
