Questions
How big is the Buttons2 waveshare eth esp32s3 PCB?
It measures 56 × 92 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Buttons2 waveshare eth esp32s3 use?
56 parts, built around the PCA9555PW, TLV1117-50IDCYRG3, BC817 and MBR0530. 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 Buttons2 waveshare eth esp32s3 KiCad files?
From the FlamingLotusGirls/haven repository on GitHub, at the commit this page was made from: the board is Fire/ButtonIntercept_v3.0/waveshare_eth_esp32s3/buttons2_waveshare_eth_esp32s3/buttons2_waveshare_eth_esp32s3.kicad_pcb and its schematic Fire/ButtonIntercept/Haven_buttons1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Buttons2 waveshare eth esp32s3 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
