Questions
How big is the Arduino Trainer PCB?
It measures 150 × 150 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arduino Trainer use?
40 parts, built around the COM-09032. 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 Arduino Trainer KiCad files?
From the foxbat01/Arduino_Easy_Trainer_PCB repository on GitHub, at the commit this page was made from: the board is Arduino_Trainer.kicad_pcb and its schematic Arduino_Trainer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Arduino Trainer design in my own project?
Its repository states no licence, so its author keeps all rights: ask foxbat01 before reusing the design.
