Re: What makes Naza 'better' than Multiwii

We all are very proud of our multiwii boards but I have seen many naza here in italy and I think that my multiwii, for example, after days and days of setup still doesn't have the baro stability and the gps stability of the naza.

Re: Tiny-GPS integrated into Multiwii (GPS/Sonar/Optical to

The more devices your I²C bus has, the longer the wires are, the higher the electrical bus capacity gets. This means that it takes longer for the pull up resistors to re-charge the bus after it has been pulled down. You can also try to slow down the bus (if you are using 400kHz). I am testing diffe...
