Questions
How big is the PCB Cuarto PCB?
It measures 90 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the PCB Cuarto use?
79 parts, built around the ESP32-S3-WROOM-1-N8, R-78K12-2.0, THVD2450VDRCREP and TPS26631PWP. 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 PCB Cuarto KiCad files?
From the Jose-WaitNRest/PCB-Cuarto repository on GitHub, at the commit this page was made from: the board is PCB/PCB-Cuarto.kicad_pcb and its schematic PCB/MCU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PCB Cuarto design in my own project?
Its repository states no licence, so its author keeps all rights: ask Jose-WaitNRest before reusing the design.
