Questions
How big is the DigitalClock ATMega328 PCB?
It measures 68.9 × 50.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the DigitalClock ATMega328 use?
74 parts, built around the ATMEGA16U2-MU, ATMEGA328P-MU, LMV358IDGKR and LP2985-33DBV. 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 DigitalClock ATMega328 KiCad files?
From the bostang/PCBs repository on GitHub, at the commit this page was made from: the board is Digital Clock/DigitalClock_ATMega328.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the DigitalClock ATMega328 design in my own project?
Its repository states no licence, so its author keeps all rights: ask bostang before reusing the design.
