Hello out there,
Please could some provide me with the dimensions for the APM2.0 board including GPS daughter board? Dimensions with / without the optional case would be very helpfull.
Additionaly are there any standard recommendations for mounting from the perspective of vibration? I want to mount the unit in a trex 450 FBL (tradheli) first then perhaps purchase / scratch build a quadcopter later. Vibration damping for a traditional helicopter is perhaps off topic for this section but an understanding of the overall sensitivity of the unit to vibration would be very useful.
Sorry if this info is already on the site / shop - I looked everywhere I could think but couldn't find it.
Thanks in advance
Henry

Here are two more of my build with 90 degree connectors. Straight up connectors would, of course, be contained inside the boundaries of the board edges.
The variations of the actual pcb to the Eagle data is probably due to machining/routing tolerances.
In both pictures, the leftmost edge of the pins is aligned with the left ruler. Parallax prevents complete accurate alignment photos and I don't want to shoot that many pictures anyway! ;) I shifted the bottom of the board up so that the through hole pins aligned with the ruler edge.
I will not break out my digital calipers to collect more data. :P
Regards!
Here you go... a photo rather than a scan (shot under fluorescent lamp thus the yellow tint).
I hope it helps. The xxx,yyy numbers refer to the Eagle coordinates as listed in the drawing. You can see the dark circled hole indicators as the corrected locations. I used the actual APM2 to correct the dimension of the template (trimmed with X-Acto knife) but did not correct the Eagle values written on the template. As I mentioned, the actual pcb finished off a few millimeters off my initial template.
Eagle is free (limited pcb size) and the learning curve is not too bad. There are plenty of tutorials online.

I had to find dimensions off the Eagle drawing of the pcb, then made a card template with mounting holes included.
It was a few millimeters off the actual size (and mounting holes too) of the APM2 once mine arrived and I corrected the card template.
The template did not include the vertical (Z) dimension but just the foot print. The purpose was to 'fit' the APM2 into another airframe currently under construction (not blogged... yet).
If you think it useful, it could be scanned with a 0.01 inch grid paper background and I could post it here or online.
