Questions
How big is the Gravitymon zero adapter PCB?
It measures 27 × 31 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gravitymon zero adapter use?
7 parts. 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 Gravitymon zero adapter KiCad files?
From the mp-se/pcb-designs repository on GitHub, at the commit this page was made from: the board is gravitymon_zero_adapter/gravitymon_zero_adapter.kicad_pcb and its schematic gravitymon_pet_zero/gravitymon_pet_zero.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gravitymon zero adapter design in my own project?
Its repository states no licence, so its author keeps all rights: ask mp-se before reusing the design.
