Assembly

The mechaical design was done in Fusion 360. The assemby files can be found in CAD files as .f3z and .step files. STL files for direct 3D Printing can be found on Thiniverse.

The electrical design was made with EasyEDA. The files for the PCB can either be found in the folder PCB files or you can order them directly here: https://oshwlab.com/patrick.harrer94/open-autopilot

A wiring diagram for the connection between arduino and PCB or for manual wiring can be also found in the PCB fiels folder.
