Questions
How big is the Signalgenerator rounded PCB?
It measures 78 × 57 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Signalgenerator rounded use?
36 parts, built around the CH32V003F4P6, CH32V003J4M6, AMS1117-3.3 and SK6805E-J. 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 Signalgenerator rounded KiCad files?
From the roboter/Hardware repository on GitHub, at the commit this page was made from: the board is WCH/KiCAD/SignalGenerator/SignalGenerator/signalgenerator-rounded.kicad_pcb and its schematic PROJECTS/LORAWAN LR1262/LR1262/LR1262.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Signalgenerator rounded design in my own project?
Its repository states no licence, so its author keeps all rights: ask roboter before reusing the design.
