My Name is Sebastian and im 16 Years old and from Germany. I fly Multicopters for 1Year now and my newest Project is an Oktocopter.
But now to my Problem:
I´m serching an GPS Module.
I use an Flyduino, so I can use I2C and serial.
What is better? I2C or serial?
I think I can use I2C at an 168 too, so its more compatible to other Copters.
Can I use every GPS Module with NMEA and TTL ?
Is it necessarily to update every GPS Modul, even when it alredy works with 10Hertz?
If I want to use Sonar, I must use an external Mikrocontroller?
Or can I use a Sonar directly at the FC?
