Solo? Yea, its a beautiful machine with some really nice functionality...
How can I make this work on any random rig I want to build, thats cooler than theirs?
Well, this is a bit of a complicated question but removing the abstraction of the frame, motors, and ESC's, theres the flight controller (Pixhawk2), and then the onboard computer (AKA SoloLink) which accomplishes the following:
1. Pushes flight instructions to the FC, and video instructions to the camera
2. Forms an 802.11 AP interface with the controller, and
3. Ingests HDMI video from a gopro (or reasonable facsimile) & using gstreamer, pushes this across the formed wifi link to an android or iWhatever device
Thats pretty awesome, how do you know all of this?

Ive tried looking around for small form factor boards & cant seem to find anything that does HDMI IN ?!?!?!?FTW?!?!?!?
Yea, same here until just recently... http://www.gateworks.com/product/item/ventana-gw5510-single-board-computer
HDMI In, Canbus, not really much on storage, but does wifi by way of a mPCIe slot (Which... if you look around on amazon for laptop upgrades, theres plenty that do 802.11AC that can be found fairly cheap). I would imagine that this (or something close to it) wound up being used as a proof of concept platform for what the solo is built upon?
They have a newer board (the Ventana 5530) which looks more appealing, has more horsepower, has GPS & 9DoF -But lacks HDMI in, canbus, and I2C
Anyways, my question to the community becomes... for purposes of interfacing & communicating with Pixhawk, is canbus the only interface/protocol here or are there other things in play here?
