Questions
How big is the Atmega32 PCB?
It measures 97.5 × 58 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Atmega32 use?
49 parts, built around the ATMEGA328P-AU, CH340C, 24LC1025-I/P and AMS1117-3.3. 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 Atmega32 KiCad files?
From the George-Emad31/Pcb repository on GitHub, at the commit this page was made from: the board is Pcb designs/atmega32/atmega32.kicad_pcb and its schematic Pcb designs/1/power supply/power supply.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Atmega32 design in my own project?
Its repository states no licence, so its author keeps all rights: ask George-Emad31 before reusing the design.
