Questions
How big is the MioLink PCB?
It measures 53 × 42 mm and has 4 copper layers, 1.66 mm thick.
What parts does the MioLink use?
117 parts, built around the RP2040, LMV321IDCKR, TLV62568DBV and W25Q16JVSSIQ. 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 MioLink KiCad files?
From the Misaka0x2730/MioLink repository on GitHub, at the commit this page was made from: the board is hardware/revB/MioLink.kicad_pcb and its schematic hardware/MioLink_Pico/revA/MioLink_Pico.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MioLink design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
