[Paparazzi-devel] which GPS module for Lisa/M

[alonso acuña]

Hi. We're planning on getting a Lisa/M or Lia board for a fixed wing and need to pick a GPS module.

I have seen these two:

Apparently the second one is 3.3V only.  Lisa board is giving 5V but I understand that with a jumper change this can be changed to 3.3V. Correct?

Also I am a bit confused about the antennas. Which one is better? Is it recommended to get an additional antenna? What would be the best way to position these on the airframe?

Is there some other better option?

Thanks
