Quadrotor layout

From the previous post you can see that the hardware design is complete in the form of a schematic, which only specifies how things are connected but not in a specific physical layout. That’s done in the separate step where you arrange the parts and connect them, according to the schematic, using board (as in printed circuit board or PCB) layout software. I’m using the free CadSoft EAGLE which works very well for both schematics and layouts.

Nothing fancy, a two-layer design making a roughly 2“x3” board. This will go right on the central platform of the quadrotor. Already sent out to my go-to board manufacturer Advanced Circuits which take my files and make a high quality circuit board ready for parts assembly.
