Questions
How big is the E Latch PCB?
It measures 43.2 × 68.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the E Latch use?
16 parts, built around the LM1117-3.3 and RJ45. 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 Latch KiCad files?
From the bgerp/ztm_doc repository on GitHub, at the commit this page was made from: the board is PCBs/E-Latch/E-Latch_Type2/E-Latch.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the E Latch design in my own project?
Its repository states no licence, so its author keeps all rights: ask bgerp before reusing the design.
