Questions
How big is the Placa madre esp32s3 uno PCB?
It measures 195 × 159 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Placa madre esp32s3 uno use?
128 parts, built around the 74HCT541D, BTA24-800BW, MAX6675ISA+ and ADS1115IDGSR. 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 madre esp32s3 uno KiCad files?
From the Chavacastro98/Proyecto repository on GitHub, at the commit this page was made from: the board is hardware/pcb/placa_madre_esp32s3_uno/placa_madre_esp32s3_uno.kicad_pcb and its schematic hardware/pcb/placa_madre_esp32s3_uno/placa_madre_esp32s3_uno.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Placa madre esp32s3 uno design in my own project?
Its repository states no licence, so its author keeps all rights: ask Chavacastro98 before reusing the design.
