Questions
How big is the ALTERNANCIA PI PICO PCB?
It measures 150 × 100 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ALTERNANCIA PI PICO use?
125 parts, built around the TMH 0505S, 74HC595, ULN2003 and PN2222A. 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 ALTERNANCIA PI PICO KiCad files?
From the zen451019/EMASA_drivers repository on GitHub, at the commit this page was made from: the board is Schematics/ALTERNANCIA_PI_PICO/ALTERNANCIA_PI_PICO.kicad_pcb and its schematic Schematics/ALTERNANCIA_PI_PICO/ALTERNANCIA_PI_PICO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ALTERNANCIA PI PICO design in my own project?
Its repository states no licence, so its author keeps all rights: ask zen451019 before reusing the design.
