Questions
How big is the Atmega328 Coursera PCB?
It measures 58 × 41.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Atmega328 Coursera use?
24 parts, built around the ATMEGA328P-AU and AMS1117. 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 Atmega328 Coursera KiCad files?
From the csvalderrama/pcb_Design repository on GitHub, at the commit this page was made from: the board is Atmega328_Coursera/Atmega328_Coursera.kicad_pcb and its schematic Atmega328_Coursera/Atmega328_Coursera.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atmega328 Coursera design in my own project?
Its repository states no licence, so its author keeps all rights: ask csvalderrama before reusing the design.
