Questions
How big is the LanghuaTestBoard PCB?
It measures 130.8 × 199.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LanghuaTestBoard use?
126 parts, built around the FM33LE026, DRV8837DSG, P25Q32H-SUH-IR and TTP233H-BA6. 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 LanghuaTestBoard KiCad files?
From the JsonJiu/WX repository on GitHub, at the commit this page was made from: the board is Sanchuan_NB_ValveCtrl/Document/工装/LanghuaTestBoard/LanghuaTestBoard.kicad_pcb and its schematic Sanchuan_NB_ValveCtrl/Document/PCB&Scheme/PMTF/PMTF.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the LanghuaTestBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask JsonJiu before reusing the design.
