Questions
How big is the V2CheapToPanel PCB?
It measures 120 × 116 mm and has 2 copper layers, 1.6 mm thick.
What parts does the V2CheapToPanel use?
398 parts, built around the MMBFJ112. 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 V2CheapToPanel KiCad files?
From the TychoJ/simpleBJTtia repository on GitHub, at the commit this page was made from: the board is hardware/v2Cheap/panel/v2CheapToPanel.kicad_pcb and its schematic hardware/V4/4resTia.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the V2CheapToPanel design in my own project?
Its repository states no licence, so its author keeps all rights: ask TychoJ before reusing the design.
