Questions
How big is the Sango PCB?
It measures 303.3 × 119 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Sango use?
325 parts, built around the RP2040, W25Q16JVUXIQ, USBLC6-2P6 and XC6210B332MR. 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 Sango KiCad files?
From the Aidan-OS/Sango repository on GitHub, at the commit this page was made from: the board is PCB/Sango/Sango.kicad_pcb and its schematic PCB/Sango/Left_Matrix.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sango design in my own project?
Its repository publishes it under the Apache-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).
