Questions
How big is the IS903 PCB?
It measures 33 × 14 mm and has 4 copper layers, 1.6 mm thick.
What parts does the IS903 use?
31 parts. 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 IS903 KiCad files?
From the prashant87/IS903 repository on GitHub, at the commit this page was made from: the board is kicad(弃用)/IS903/IS903.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the IS903 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).
