Questions
How big is the Proyecto Chaleco 7mo 3ra PCB?
It measures 60.5 × 35.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Proyecto Chaleco 7mo 3ra use?
24 parts, built around the ESP-WROOM-32D, DS18B20, MAX30102 and AMS1117-3.3. 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 Proyecto Chaleco 7mo 3ra KiCad files?
From the Toxtxo19/proyect-vest repository on GitHub, at the commit this page was made from: the board is HARDWARE/Main/Proyecto Chaleco 7mo 3ra.kicad_pcb and its schematic HARDWARE/Main/Proyecto Chaleco 7mo 3ra.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Proyecto Chaleco 7mo 3ra design in my own project?
Its repository states no licence, so its author keeps all rights: ask Toxtxo19 before reusing the design.
