Questions
How big is the Herringbone Pro PCB?
It measures 314.3 × 143.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Herringbone Pro use?
220 parts, built around the ATMEGA32A-PU. 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 Herringbone Pro KiCad files?
From the ramonimbao/Herringbone-Pro repository on GitHub, at the commit this page was made from: the board is HerringbonePro.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Herringbone Pro design in my own project?
Its repository states no licence, so its author keeps all rights: ask ramonimbao before reusing the design.
