If I break down the platform it will have two sets:
- electronics that I will design and build (assembled electronic cards)
- mechathings the cots items for mechanical, assembly tools, brushless motors,...
- batteries
- software the SDK for the SAME70 and the Raspberry Pi Compute Module

The main composition can be described in the following breakdown structure.

The main part that requires lot of works is the software part to setup a SDK to make easy the software development on the drone, I will start it as soon as I finish the hardware design.
But now we focus on the hardware thing :)

The following detailed breakdowns will gather also the user needs of the composition of the platform.
