Questions
How big is the Project 1 PCB?
It measures 76.3 × 54.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Project 1 use?
21 parts, built around the L298N. 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 1 KiCad files?
From the AJ-returns/PCB repository on GitHub, at the commit this page was made from: the board is Motor Drivers/.history/Project 1.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 1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask AJ-returns before reusing the design.
