Questions
How big is the Esp32 example PCB?
It measures 57.3 × 79.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Esp32 example use?
104 parts, built around the ESP32-S3-WROOM-1-N16R2, INA240A1D, MAX14871EUE+ and OPA2340PA. 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 Esp32 example KiCad files?
From the csteber02/ECE-445 repository on GitHub, at the commit this page was made from: the board is esp32_example_rev_A/esp32_example.kicad_pcb and its schematic Final Project V1/Final Project V1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Esp32 example design in my own project?
Its repository states no licence, so its author keeps all rights: ask csteber02 before reusing the design.
