Questions
How big is the Thelio io PCB?
It measures 96 × 28 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Thelio io use?
78 parts, built around the RP2040, W25Q16JVSSIQ, LP5907MFX-3.3 and BSS138PW. 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 Thelio io KiCad files?
From the system76/thelio-io-hardware repository on GitHub, at the commit this page was made from: the board is pcb-thelio-io/thelio-io.kicad_pcb and its schematic pcb-nebula-io/nebula-io.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Thelio io 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).
