Questions
How big is the Stage-3 PCB?
It measures 35.1 × 24.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Stage-3 use?
7 parts, built around the ATMEGA328P-AU and IRF540N. 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 Stage-3 KiCad files?
From the Aditya-8368/Aditya repository on GitHub, at the commit this page was made from: the board is Stage-3.kicad_pcb and its schematic Stage-3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Stage-3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Aditya-8368 before reusing the design.
