PI 3 Fan without using GPIO

Sat Nov 26, 2016 2:55 am

I haven't even received my PI 3 but I thought I would ask as after some googling I decided on a Pibow coupe case and decided against a fan because I don't want to use the GPIO fans.

What I did do was search for alternative pins for VCC5 & Gnd TP1&2 don't exist anymore and looking at things it would seem there isn't anywhere easily accessible without making adding a header and fan a relatively messy affair.

Apols about using this section but 'interfacing to power' :)

Well, maybe you should use the time for getting idea where to look for hardware related data.
I would start with having a look at the Raspberry Pi (whatever version) schematic to see what is available and where.
The schematics are in the documentation section https://www.raspberrypi.org/documentati ... /README.md

Doing this would have revealed: there are lot of options for getting 5V from test pins on the bottom of the RPi3
