Questions
How big is the MasterModule PCB?
It measures 50 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the MasterModule use?
22 parts, built around the TJA1051T, ADUM1201AR, AMS1117-3.3 and AMS1117-5.0. 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 MasterModule KiCad files?
From the dmitry131131/PumpSystem repository on GitHub, at the commit this page was made from: the board is MasterModule/PCB/MasterModule/MasterModule/MasterModule.kicad_pcb and its schematic MasterModule/PCB/Bus/BusModule/BusModule.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MasterModule design in my own project?
Its repository states no licence, so its author keeps all rights: ask dmitry131131 before reusing the design.
