A³ Assembly
The A³ devices are built by hand from parts anyone can get. The boards are designed in KiCad
and ordered from a PCB manufacturer from the production files in each device’s repository
(hardware/pcb/<revision>/), then fitted by hand. The housings are designed in FreeCAD and
printed on an ordinary FDM 3D printer (hardware/housing/). The shared parts library for the
boards is a3-kicad-lib.
What belongs to which version — every repository, board revision and housing — is on the A³ System page.
