Questions
How big is the Arnavipdtask1 PCB?
It measures 120 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Arnavipdtask1 use?
47 parts, built around the ATMEGA328P-PU, ULN2803A 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 Arnavipdtask1 KiCad files?
From the arnav1609/PCBDESIGNING repository on GitHub, at the commit this page was made from: the board is Arnavipdtask1.kicad_pcb and its schematic ArnavBhandariipdtask1avr.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Arnavipdtask1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask arnav1609 before reusing the design.
