Questions
How big is the Wire connect checker PCB?
It measures 53.5 × 69.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Wire connect checker use?
73 parts, built around the CH32V003F4P6, AMS1117 and CH213K. 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 Wire connect checker KiCad files?
From the 74th/74th-oshw-projects repository on GitHub, at the commit this page was made from: the board is 74TH-G057-diy_cable_checker/wire_connect_checker.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Wire connect checker 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).
