Questions
How big is the Trial PCB?
It measures 53.8 × 36.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Trial use?
29 parts, built around the LM358, TIP31 and TIP32. 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 Trial KiCad files?
From the koson/KicadProject repository on GitHub, at the commit this page was made from: the board is WSC Trial for the jokers/Trial.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Trial design in my own project?
Its repository states no licence, so its author keeps all rights: ask koson before reusing the design.
