Questions
How big is the Rte rpi PCB?
It measures 104 × 57.9 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rte rpi use?
44 parts, built around the MAX3232ID, MCP23017-E/SS and NDS351AN. 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 Rte rpi KiCad files?
From the 3mdeb/RTE-for-RPI-Schematics repository on GitHub, at the commit this page was made from: the board is kicad-files/rte_rpi.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rte rpi design in my own project?
Its repository states no licence, so its author keeps all rights: ask 3mdeb before reusing the design.
