Questions
How big is the Alpha curISO PCB?
It measures 248.6 × 81.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Alpha curISO use?
241 parts, built around the RP2040, 74AHCT1G125SE, W25Q128JVSIQ and USBLC6-2SC6. 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 Alpha curISO KiCad files?
From the calvin-mcd/alpha-curISO repository on GitHub, at the commit this page was made from: the board is Project/alpha-curISO.kicad_pcb and its schematic Project/Components.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Alpha curISO design in my own project?
Its repository states no licence, so its author keeps all rights: ask calvin-mcd before reusing the design.
