Questions
How big is the Backbone PCB?
It measures 90 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Backbone use?
39 parts, built around the SN74LVC2G14DBV and SM4001. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Backbone KiCad files?
From the cegep-electronique-programmable/backbone repository on GitHub, at the commit this page was made from: the board is backbone.kicad_pcb and its schematic alimentations.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Backbone design in my own project?
Its repository states no licence, so its author keeps all rights: ask cegep-electronique-programmable before reusing the design.
