Questions
How big is the Adapter1 PCB?
It measures 56.8 × 90 mm and has 2 copper layers, 0.07 mm thick.
What parts does the Adapter1 use?
40 parts, built around the ATECC608B-SSHDA-T, MBR0530, AO3401A and BSS138. 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 Adapter1 KiCad files?
From the BBBSnowball/fw16 repository on GitHub, at the commit this page was made from: the board is electrical/adapter2/adapter1.kicad_pcb and its schematic electrical/adapter1/adapter1/adapter1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Adapter1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask BBBSnowball before reusing the design.
