Questions
How big is the Onboarding PCB?
It measures 75 × 75 mm and has 4 copper layers, 1.58 mm thick.
What parts does the Onboarding use?
56 parts, built around the ESP32-S3-WROOM-1-N8, ASM330LHHXTR, LM1117DT-3.3 and STEF12SAGR. 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 Onboarding KiCad files?
From the Pandas020/Onboarding repository on GitHub, at the commit this page was made from: the board is onboarding.kicad_pcb and its schematic onboarding.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Onboarding design in my own project?
Its repository states no licence, so its author keeps all rights: ask Pandas020 before reusing the design.
