Questions
How big is the WireCutter PCB?
It measures 99 × 91 mm and has 2 copper layers, 1.6 mm thick.
What parts does the WireCutter use?
204 parts, built around the CY8C4245AXI-483, ZXCT1009FTA, 25LC640A-I/SN and 74LVC4245AD. 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 WireCutter KiCad files?
From the hexeguitar/AutomatedWireCutter repository on GitHub, at the commit this page was made from: the board is hardware/AutomatedWireCutter_KiCAD/WireCutter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the WireCutter design in my own project?
Its repository states no licence, so its author keeps all rights: ask hexeguitar before reusing the design.
