Questions
How big is the AtMega32 Dev Kit PCB?
It measures 114 × 136 mm and has 2 copper layers, 1.6 mm thick.
What parts does the AtMega32 Dev Kit use?
62 parts, built around the ATMEGA32A-PU and L7805. 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 Dev Kit KiCad files?
From the namit-seth/ATmega32-Development-Board repository on GitHub, at the commit this page was made from: the board is AtMega32_Dev_Kit.kicad_pcb and its schematic AtMega32_Dev_Kit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the AtMega32 Dev Kit design in my own project?
Its repository states no licence, so its author keeps all rights: ask namit-seth before reusing the design.
