Thank you very much Sergey,
I have missed that this board already has the F4! So the port to that micro within ppz should be straightforward with another board.
Unfortunately, I am aiming at fixed wings. And one of my requirements is to have the radio at another place (waste of space and weight), and the board is a little bit big for my plane.
And also, sd card slot, DC/DC and other stuff that I would not like to make in separated boards.
Nevertheless, I would take a lot of code from that board in other to save time for making full compatible with ppz.
Regards,
Héctor
