Questions
What parts does the Circuito pcb del reloj use?
13 parts, built around the MAX30102, MPU-6050 and TP4056-42-ESOP8. 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 Circuito pcb del reloj KiCad files?
From the impatrq/NERA repository on GitHub, at the commit this page was made from: the board is circuitos/circuito pcb del reloj.kicad_pcb and its schematic circuitos/Circuito esquematico del reloj.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Circuito pcb del reloj design in my own project?
Its repository states no licence, so its author keeps all rights: ask impatrq before reusing the design.
