Questions
How big is the RMTS PCB?
It measures 78.1 × 50.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the RMTS use?
84 parts, built around the MK20DX256VLH7, ADS1219IPW, LTV-817S and PMV20ENR. 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 RMTS KiCad files?
From the reilleya/RMTS-Hardware repository on GitHub, at the commit this page was made from: the board is RMTS.kicad_pcb and its schematic RMTS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the RMTS design in my own project?
Its repository states no licence, so its author keeps all rights: ask reilleya before reusing the design.
