Questions
How big is the Require PCB?
It measures 68 × 26 mm and has 6 copper layers, 1 mm thick.
What parts does the Require use?
180 parts, built around the PAM2305CGFADJ, ATECC608A-MAHDA-S, PESDUC3FD5VU and AH104N2450D1-T. 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 Require KiCad files?
From the facethesouth/require repository on GitHub, at the commit this page was made from: the board is hardware/require.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Require design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
