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 herehttp://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.

@xemone, the PDB should power a PI zero, but I tried this with a PI3 and it failed. Not enough current output. I use a separate regulator now.  


Thanks for the advice.

Also, you're right about the RPi Zero. I've had it for a while and will try it out before deciding to get a RPi 3 or not. The 3A current should be more than enough for any RPi.

@xemone that's a really neat PDB.  You should have no problem going from regulated 5v output straight to the IO gnd/vin pins.  If you want to be paranoid you can go in through the usb as it provides extra protection and polyfuse, but really no need from the PDB BEC.

BTW, don't expect too much performance from pi zero + opencv!!!
