Questions
How big is the Julio cool clock PCB?
It measures 140 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Julio cool clock use?
60 parts, built around the MAX7219M, ED281DT, L7805CDT-TR and B3FS-1000P. 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 Julio cool clock KiCad files?
From the jaramirez10/jramirez-clock repository on GitHub, at the commit this page was made from: the board is julio_cool_clock/julio_cool_clock.kicad_pcb and its schematic julio_cool_clock/julio_cool_clock.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Julio cool clock design in my own project?
Its repository states no licence, so its author keeps all rights: ask jaramirez10 before reusing the design.
