Questions
How big is the Spisolator v1 PCB?
It measures 58.4 × 18.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Spisolator v1 use?
12 parts, built around the BAT60A. 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 Spisolator v1 KiCad files?
From the 9elements/SPIsolator repository on GitHub, at the commit this page was made from: the board is spisolator_v1/spisolator_v1.kicad_pcb and its schematic spisolator_v1/spisolator_v1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Spisolator v1 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).
