Questions
How big is the Hall2040 PCB?
It measures 50.8 × 45.7 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Hall2040 use?
46 parts, built around the RP2040, GH39FKSW, 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 Hall2040 KiCad files?
From the plushugh/hall2040 repository on GitHub, at the commit this page was made from: the board is hall2040.kicad_pcb and its schematic hall2040.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Hall2040 design in my own project?
Its repository states no licence, so its author keeps all rights: ask plushugh before reusing the design.
