Hi,

I'm very pleased to join this Forum. I'm a newbies using Ardupilot APM 2.0 and after a long long weeks awaiting my board, I have received it, 2 weeks ago !!! Ordered on january.

I have discovered problems on JP1 PIN weldind and 3.3 Volts CMS not correctly welded too and 2 Ground PIN's on GPS piggy back board not welded too.

It seems working correctly too, but what about the MTBF (Mean Time Between Failure) on the future ?

I have corrected the JP1 Pin not welded, but 3.3 V G3.3 128 CMS is too difficult to manage with my fingers ... I leave as it the 2 Ground Pin's (seems always not welded).

Firmware Arducopter 2.4.5 and Mission Planner 1.1.75 loaded yesterday night.

Voltages with USB  : 4.88 Volts on 5V rail and 3.62 Volts on 3.3 V pinout ! Seems ok but a little under or over the normal status.

Do you have experienced same problems on reliability ?

GPS seems unstable on 3DFIX too on Mission Planner (inside my home near a windows).

Any information about it too ?

Thanks for feedback,

Rosario
