Questions
How big is the Esp i2c PCB?
It measures 50 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp i2c use?
21 parts, built around the ESP32-WROOM-32. 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 Esp i2c KiCad files?
From the v0l/esp32_sens repository on GitHub, at the commit this page was made from: the board is esp_i2c.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp i2c design in my own project?
Its repository states no licence, so its author keeps all rights: ask v0l before reusing the design.
