Questions

How big is the SP110Duo PCB?

It measures 457.4 × 132 mm and has 2 copper layers, 1.6 mm thick.

What parts does the SP110Duo use?

309 parts, built around the RP2040, 74AHC1G125GW, W25Q128JVSIQ and AZ1117H-3.3TRE1. 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 SP110Duo KiCad files?

From the printsmith/keyboards repository on GitHub, at the commit this page was made from: the board is SP110duo/v1/SP110Duo.kicad_pcb and its schematic SP110duo/dev/SP110Duo.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the SP110Duo design in my own project?

Its repository states no licence, so its author keeps all rights: ask printsmith before reusing the design.
