Questions
How big is the Test stand PCB?
It measures 75.7 × 61 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Test stand use?
21 parts, built around the HX711, MPXV7002DP and XT90PW-F. 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 Test stand KiCad files?
From the Ventratrat/test-stand repository on GitHub, at the commit this page was made from: the board is test.kicad_pcb and its schematic test.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Test stand design in my own project?
Its repository states no licence, so its author keeps all rights: ask Ventratrat before reusing the design.
