Questions
How big is the Latch PCB?
It measures 90 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Latch use?
19 parts, built around the IRLML6401. 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 Latch KiCad files?
From the cmdc0de/yet-another-processor repository on GitHub, at the commit this page was made from: the board is hw/latch/latch.kicad_pcb and its schematic hw/adder/adder.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Latch 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).
