Questions
How big is the WINTER PCB?
It measures 52 × 34 mm and has 6 copper layers, 1.54 mm thick.
What parts does the WINTER use?
109 parts, built around the STM32H725RGV6, MAX-M10S-00B, SKY66105-11 and SX1262IMLTRT. 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 WINTER KiCad files?
From the SparrowTheNerd/WINTER-KiCAD repository on GitHub, at the commit this page was made from: the board is WINTER.kicad_pcb and its schematic Datasheets etc/SX1262/SX1262-IPD-Design/SX126xIPD_868-915MHz_Altium_PCB_Package/IPD_KiCAD/IPD_KiCAD.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the WINTER 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).
