Questions
How big is the Gbastn PCB?
It measures 39 × 45 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Gbastn use?
66 parts, built around the RP2040, AP3015, FM25Q04-DN-T-G and LM324. 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 Gbastn KiCad files?
From the zephray/GbaStnMod repository on GitHub, at the commit this page was made from: the board is hardware/gbastn.kicad_pcb and its schematic hardware/gbastn.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Gbastn design in my own project?
Its repository states no licence, so its author keeps all rights: ask zephray before reusing the design.
