Questions
How big is the Generic bottom test jig PCB?
It measures 88.5 × 56.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Generic bottom test jig use?
49 parts, built around the 74LS257PC, STMPS2151S and TLV70233DBV. 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 Generic bottom test jig KiCad files?
From the chickadee-tech/g-test-bot repository on GitHub, at the commit this page was made from: the board is pcb/generic-bottom-test-jig.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Generic bottom test jig design in my own project?
Its repository states no licence, so its author keeps all rights: ask chickadee-tech before reusing the design.
