Questions
How big is the ICEDevBoard PCB?
It measures 100 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the ICEDevBoard use?
237 parts, built around the ICE40HX8K-BG121, SN74LV1T34DBV, W25Q32JVSSIQ and MSD-1-A. 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 ICEDevBoard KiCad files?
From the ddraig68k/ICE40DevBoard repository on GitHub, at the commit this page was made from: the board is ICEDevBoard.kicad_pcb and its schematic ICEDevBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ICEDevBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask ddraig68k before reusing the design.
