Questions
How big is the Placa PCB?
It measures 58.5 × 40.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Placa use?
81 parts, built around the ATMEGA328P-AU, CH340G, GL850G and MPU-9250. 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 Placa KiCad files?
From the ArthurMLago/botwJoystickGyro repository on GitHub, at the commit this page was made from: the board is placa/placa.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Placa design in my own project?
Its repository states no licence, so its author keeps all rights: ask ArthurMLago before reusing the design.
