Questions
How big is the UWB ESP32S3 MainBoard v2 PCB?
It measures 90 × 90 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UWB ESP32S3 MainBoard v2 use?
43 parts, built around the ESP32-S32MB, 0.1UF 50V 5*11 and BNO085. 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 UWB ESP32S3 MainBoard v2 KiCad files?
From the Castle10K/KiCad_PCB repository on GitHub, at the commit this page was made from: the board is UWB_ESP32S3_MainBoard_v2/UWB_ESP32S3_MainBoard_v2/UWB_ESP32S3_MainBoard_v2.kicad_pcb and its schematic MainBoard/MainBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UWB ESP32S3 MainBoard v2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Castle10K before reusing the design.
