Questions
How big is the PrototypeRTDBoard PCB?
It measures 60.1 × 48.1 mm and has 4 copper layers, 4.69 mm thick.
What parts does the PrototypeRTDBoard use?
71 parts, built around the LTC2452IDDB#TRMPBF, MCP6231-E/MC, MCP23S08-E/P and MIC5365-3.3YC5-TR. 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 PrototypeRTDBoard KiCad files?
From the SBC-Collaboration/SBC-RTD-Boards repository on GitHub, at the commit this page was made from: the board is PrototypeRTDBoard/PrototypeRTDBoard.kicad_pcb and its schematic PrototypeRTDBoard/PrototypeRTDBoard.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the PrototypeRTDBoard design in my own project?
Its repository states no licence, so its author keeps all rights: ask SBC-Collaboration before reusing the design.
