Prototype up and running

The prototype ( test model, codename "art2b" ) is up and running now. Raspberry Pi0w is connected to Pixhawk with PX4 stack by GPIO cable. For test purposes it powered from regular power bank with 2 USB ports but it`s enough to perform all next tests. PI camera is the same as for my previous construction - v1.3. Whole this model is connected to internet using Huawei modem of course.

There is lack of frame, motors and radio but I do not see a problem with it right now because all next changes are related PI OS and PX4 firmware.

I think if PX4 will work well on prototype I will flash by PI3 soon also to enable virtual joysticks asap :)
