Questions
How big is the Padd PCB?
It measures 128.6 × 120.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Padd use?
100 parts, built around the RP2040, W25Q128JVSIQ and SRV05-4. 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 Padd KiCad files?
From the Bankst/keebs repository on GitHub, at the commit this page was made from: the board is padd/padd.kicad_pcb and its schematic padd/padd.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Padd design in my own project?
Its repository states no licence, so its author keeps all rights: ask Bankst before reusing the design.
