Questions
How big is the Fat Cap V2 PCB?
It measures 51.9 × 114.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Fat Cap V2 use?
21 parts, built around the SIM800L. 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 Fat Cap V2 KiCad files?
From the JCP-Team/SIM800L_VERSION_FATCAP repository on GitHub, at the commit this page was made from: the board is PCB/Fat-Cap-V2.kicad_pcb and its schematic PCB/Fat-Cap-V2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Fat Cap V2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask JCP-Team before reusing the design.
