Questions
How big is the Carte mere sokko PCB?
It measures 78.5 × 54 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Carte mere sokko use?
35 parts, built around the ESP32-S3-WROOM-1-N16R8 and ICM-45686. 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 Carte mere sokko KiCad files?
From the DaVinciBot/CDR-CAD repository on GitHub, at the commit this page was made from: the board is PCB/PAMI/carte_mere_pami/carte_mere_sokko.kicad_pcb and its schematic PCB/CDR_2025/Robot_Main/carte 5V/carte 5V.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Carte mere sokko design in my own project?
Its repository states no licence, so its author keeps all rights: ask DaVinciBot before reusing the design.
