Re: Fixwing on MW2.4

Hi,

I have an old setup instruction on a blog i made a long time ago.
http://fotoflygarn.blogspot.com/2012/03 ... plane.html

But it's still Up to date.

There's also a guide for setting up for GPS there.

The Multiwii boards with Atmega 328 usually have 5V logic level.
You need a level converter to protect the PI if it don't handle 5V.
Logic Level Convert can be found everywhere on Ebay etc ( Logic Level Converter Module Bi-Directional for Arduino 5V-3V )
