Questions
What parts does the Project 2 use?
10 parts, built around the L293D. 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 Project 2 KiCad files?
From the AJ-returns/PCB repository on GitHub, at the commit this page was made from: the board is Motor Drivers/L293D/Project 2.kicad_pcb and its schematic AQI/.history/AQI.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Project 2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask AJ-returns before reusing the design.
