What's new:
- new GPS sensor selection procedure: put jumper on pin number 5 and 6 to use Naza GPS. If no jumper is set - external Ublox GPS sensor supposed to be used.

v 0.04

Finally, I finished new v 0.04 board design and sent it to production. Another month to wait for delivery (and another vacation to spend, this time in Greece).
Meanwhile I have a plenty of time to design a plastic case and hopefully find a reasonable offer to make it injection moulded.
So it's getting closer to the final product in the way it should be.
