Questions
How big is the Termometro digital fabricio PCB?
It measures 100 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Termometro digital fabricio use?
31 parts, built around the ICL7107CPL, ICL7660N, MT3608 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 Termometro digital fabricio KiCad files?
From the fab-rodrigs/digital-termometer-pcb repository on GitHub, at the commit this page was made from: the board is termometro_digital_fabricio.kicad_pcb and its schematic termometro_digital_fabricio.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Termometro digital fabricio design in my own project?
Its repository states no licence, so its author keeps all rights: ask fab-rodrigs before reusing the design.
