Questions
How big is the Philly Node PCB?
It measures 22 × 39 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Philly Node use?
77 parts, built around the E22-900M22S, MDBT50Q-U1MV2, TPS2120YFPR and TPS25200DRVT. 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 Philly Node KiCad files?
From the tasmaniandroid/Philly_Node repository on GitHub, at the commit this page was made from: the board is Philly_Node.kicad_pcb and its schematic Philly_Node.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Philly Node design in my own project?
Its repository publishes it under the CERN-OHL-S-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
