Questions
How big is the Snzagpad PCB?
It measures 74.8 × 99.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Snzagpad use?
94 parts, built around the RP2040, W25Q128JVSIQ, SRV05-4 and XC6206-2.8V. 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 Snzagpad KiCad files?
From the zykrah/snzagpad repository on GitHub, at the commit this page was made from: the board is snzagpad.kicad_pcb and its schematic snzagpad.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Snzagpad design in my own project?
Its repository states no licence, so its author keeps all rights: ask zykrah before reusing the design.
