Questions
How big is the Julis PCB?
It measures 87.3 × 53.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Julis use?
135 parts, built around the TLV62568DBV, W25Q32JVSSIQ, M24C02-WDW6TP and IRLML2502. 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 Julis KiCad files?
From the Misaka0x2730/Julis repository on GitHub, at the commit this page was made from: the board is Julis.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Julis design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
