px4 firmware

I did run and upload a px4 firmware into a new Pixhawk 2 days ago. Looks everything works fine and this process is very easy to be done using ground control. I think if everything will fine I will do it also on Radiolink Pixhawk to have 100% compatibility with ground station.

Pixhawk is calibrated now and I`m able to connect it with raspberry PI0w by GPIO UART cable. I hope this connection should work well without problems that I have had with RPI3.

As I note before all ports in both pixhawks are the same so cables between FC and Raspberry should works also well. Today I`m putting together prototype and hope it will be ready end of day.
