Questions
How big is the GCP-2 PCB?
It measures 45.3 × 26 mm and has 4 copper layers, 2 mm thick.
What parts does the GCP-2 use?
47 parts, built around the RP2040, GD25Q80EEIGR, XC6222B331PR-G and 1TS026A-1000-0550-CT. 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 GCP-2 KiCad files?
From the HandHeldLegend/GC-Adapter-RP2040 repository on GitHub, at the commit this page was made from: the board is PCB/GCP-2.kicad_pcb and its schematic PCB/GCP-2.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the GCP-2 design in my own project?
Its repository states no licence, so its author keeps all rights: ask HandHeldLegend before reusing the design.
