Questions
How big is the Testgit PCB?
It measures 106.7 × 116.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Testgit use?
51 parts, built around the CH340E, TJA1051T/3/1 and AD8400ARZ50. 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 Testgit KiCad files?
From the henDragon/testgit repository on GitHub, at the commit this page was made from: the board is 作业/作业.kicad_pcb and its schematic 作业/DigitalPotentiometer.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Testgit design in my own project?
Its repository states no licence, so its author keeps all rights: ask henDragon before reusing the design.
