The DragonBoard 410c might suit you.

I see it for $75 at one of my usual suppliers.

It has a snapdragon 410 - 1.2Ghz, 1GB RAM, Bluetooth, WiFi, etc.

However, both of these are probably huge overkill for a quadcopter.

The problem you face is twofold:

* The quadcopter needs to react in real time, so you need a real time OS.

* Machine learning can use a huge amount of memory.

The usual way to solve this, is a simplified onboard system. Crash prevention and the like. Probably an Arduino or ESP8266.

Then, that communicates with a ML system on a laptop or the like, which does the hard work.

My idea was have something like that hooked in to the bigger board via USB - the Android is creating flight plans and the micro controller is just managing the motors and following the plans it receives.

snapdragon 410 seems like it doesn't have OpenCL 2 (shared memory access ?)

The microcontroller may need more than naively doing as told, to reduce crash & burn.

For the other board, I probably wouldn't use USB, but a serial or pin connection could be faster.

Broadcom recently released the spec sheet for the Raspberry Pi's GPU, and people have been doing good work with that.

Edit: Snapdragon 410 has official support only for OpenCL 1.1

I was just thinking USB since it's guaranteed to be there and should be simple to program on android if I chose to go down the "disassemble a phone for parts" route.
