A discussion page to allow me to add my experiences using a Raspberry Pi 2/3/Zero V1.2/1.3 as a companion computer for Ardupilot/APM/Pixhawk flight boards. I will update my experiences as I learn, feel free to comment and offer tips, it's all free here.
I'm building a github for my experiments: https://github.com/benb0jangles/Companion-Pi
Drone Unit: Raspberry Pi Zero V1.3 + Pi Camera Module

Ardupilot Technical Questions:
Also, if you have any technical code/hardware questions which you feel may take ongoing contributions and help over an extended timeframe, feel free to ask over on Ardupilot.org technical discussion page here: http://discuss.ardupilot.org/t/companion-pi-2-3-zero/9460
I will update as I get by, please contribute by offering your 'plug & play' wifi adapters using Raspbian Jessie. Also, if you happen to pick up this project, and are working faster than me, then please send us your own .img file experiments. Thanks.

How to set up a static ip address for you wifi connection?
Here is a guide from the pi forums how to do this. Also information here too.
Anyone completed this for their pi2 and tested working?
Using a static ip will allow me to insert any wifi adapter into the pi without assigning a different ip. This is good for the DIY/hacker community
Sorry all, this is the hack I wanted to post, no hardware mod, only a few lines of code.

and it works, I have an Asus wifi dongle and it was not working before the hack
I placed 'max_usb_current=1' in the pi2's config.txt file. Works!

Brief comparison of pi2 size next to my TK1:
The pi2 is of course the cheap go-to board for most first timers coming to the single board computer. It probably has the most support for using peripherals, or finding out which ones work on the pi2 forums. There are some downsides to using the pi2 as it arrives though. I found that the usb ports don't really provide very much power to devices, and that can render some devices unusable without usb port modification. I found that my USB 4g dongle won't power up, or high power wifi adapters won't run as they should. I'm sure there is a hardware 5v hack possible.

ty i'll try this with my 4g dongle and report back
Did not know! Any idea is this is the same on the rpi 3?
don't know, just give it a try...
