Questions
How big is the Geophys mainboard PCB?
It measures 190 × 110 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Geophys mainboard use?
384 parts, built around the ESP32-S3-DEVKITC-1-N8, TPS61040DBV, TPS63700DRCR and AD7779ACPZ. 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 Geophys mainboard KiCad files?
From the Benjamin-girard-1/magnetometer-node-old repository on GitHub, at the commit this page was made from: the board is hardware/pcb/Expension_card_design/geophys_mainboard/geophys_mainboard.kicad_pcb and its schematic hardware/pcb/DAN_F10N_testboard/DAN_F10N_testboard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Geophys mainboard design in my own project?
Its repository states no licence, so its author keeps all rights: ask Benjamin-girard-1 before reusing the design.
