Questions
How big is the Aero pcblayout PCB?
It measures 140 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Aero pcblayout use?
21 parts. 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 Aero pcblayout KiCad files?
From the dhanupragateesh26/AERO_linefollower repository on GitHub, at the commit this page was made from: the board is Aero_pcblayout.kicad_pcb and its schematic Aero_schematic.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Aero pcblayout design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
