Questions
How big is the ICE40-Board PCB?
It measures 134.4 × 58 mm and has 4 copper layers, 4.69 mm thick.
What parts does the ICE40-Board use?
83 parts, built around the FT4222HQ-C, ICE40HX4K-TQ144, 74LS125DC and 74LS126PC. 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 ICE40-Board KiCad files?
From the SyedAnasAlam/Ice-Board repository on GitHub, at the commit this page was made from: the board is ICE40-Board.kicad_pcb and its schematic ICE40-Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ICE40-Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask SyedAnasAlam before reusing the design.
