Questions
How big is the E nez PCB?
It measures 54.8 × 83.5 mm and has 4 copper layers, 1.6 mm thick.
What parts does the E nez use?
108 parts, built around the LTC3440EMS#PBF, MPX5050GP, PCM1863QDBTRQ1 and TLV9062IDR-MS. 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 E nez KiCad files?
From the gberthou/e-nez repository on GitHub, at the commit this page was made from: the board is board/e-nez.kicad_pcb and its schematic board/e-nez.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the E nez 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).
