Questions
How big is the VColChoc44 PCB?
It measures 234 × 88 mm and has 2 copper layers, 1.6 mm thick.
What parts does the VColChoc44 use?
121 parts, built around the RP2040, W25Q128JVSIQ and AMS1117-3.3. 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 VColChoc44 KiCad files?
From the jpconstantineau/VColChoc44 repository on GitHub, at the commit this page was made from: the board is VColChoc44.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the VColChoc44 design in my own project?
Its repository states no licence, so its author keeps all rights: ask jpconstantineau before reusing the design.
