Questions
How big is the DaisyTape v2 4 layers PCB?
It measures 100.3 × 82.5 mm and has 4 copper layers, 1.58 mm thick.
What parts does the DaisyTape v2 4 layers use?
159 parts, built around the 74HCT125DB, R-78E5.0-1.0, LME49721MA and CPC1018N. 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 DaisyTape v2 4 layers KiCad files?
From the FilippoGorini/DaisyTape repository on GitHub, at the commit this page was made from: the board is hardware/pcb/DaisyTape_v2_4_layers.kicad_pcb and its schematic hardware/pcb/DaisyTape_v2_4_layers.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DaisyTape v2 4 layers design in my own project?
Its repository states no licence, so its author keeps all rights: ask FilippoGorini before reusing the design.
