Questions
How big is the Projeto PCB?
It measures 163 × 75.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Projeto use?
97 parts, built around the ESP32-S3-WROOM-1-N8, AP63203WU, LM358 and MEM2075-00-140-01-A. 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 Projeto KiCad files?
From the AlisonTristao/bally_robot repository on GitHub, at the commit this page was made from: the board is projeto_hardware/projeto.kicad_pcb and its schematic projeto_hardware/projeto.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Projeto design in my own project?
Its repository states no licence, so its author keeps all rights: ask AlisonTristao before reusing the design.
