Questions

How big is the Mradio PCB?

It measures 130.8 × 75 mm and has 6 copper layers, 1.56 mm thick.

What parts does the Mradio use?

200 parts, built around the TPS54560BDDA, 74AVC4T774PWJ, TPS7A8500ARGRR and SN74LVC1T45DRL. 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 Mradio KiCad files?

From the umrover/mradio repository on GitHub, at the commit this page was made from: the board is pcb/mradio/mradio.kicad_pcb and its schematic pcb/mradio/1v8_LDO.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Mradio design in my own project?

Its repository states no licence, so its author keeps all rights: ask umrover before reusing the design.
