Nice! Can I take advantage of you having one to help us find and communicate some info about it ?
Because I can't find the complete up-to-date schematics that at least should be available for reading by community. There are just two pdf files available on github (https://github.com/proficnc/pixhawk2.1)
-IMU_REV_1A.pdf (about the IMU sensors)
-PSM_REV_C.pdf (about power mgt)
On proficnc and partner hex.aero web sites, the technical specifications that can be found is incomplete, in particular the most basic information such as the dimensions of Pixhawk2.1 and its weight or even the chip reference of its 3-in-1 sensors (the downloadable PDF specs mention MPU92xx or ICMxx but which one is it ?)
So could we take advantage of you having one to take a look inside to tell us what IMU chips are used, and measure PixhawkV2.1's total weight and dimensions please ? I'd appreciate it very much, thanks!
