Questions
How big is the Rio tangbob PCB?
It measures 90.3 × 72.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Rio tangbob use?
71 parts, built around the MAX485ED, WIZ850IO, TXS0108EPW and 1N4148WT. 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 Rio tangbob KiCad files?
From the multigcs/rio-tangbob repository on GitHub, at the commit this page was made from: the board is rio-tangbob.kicad_pcb and its schematic iocon.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Rio tangbob design in my own project?
Its repository states no licence, so its author keeps all rights: ask multigcs before reusing the design.
