Questions
How big is the Ice4pi PCB?
It measures 65 × 30 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Ice4pi use?
57 parts, built around the ICE40HX1K-TQ144, W25Q32JVSSIQ, DSC1001DI1-012.0000 and MIC5504-1.2YM5-TR. 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 Ice4pi KiCad files?
From the lightside-instruments/ice4pi repository on GitHub, at the commit this page was made from: the board is ice4pi.kicad_pcb and its schematic ice4pi.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ice4pi design in my own project?
Its repository states no licence, so its author keeps all rights: ask lightside-instruments before reusing the design.
