Questions
How big is the SPIEX01 PCB?
It measures 50.3 × 50.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SPIEX01 use?
20 parts, built around the 74HC125D, 74HC00D and 74HC164. 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 SPIEX01 KiCad files?
From the mlab-modules/SPIEX01 repository on GitHub, at the commit this page was made from: the board is hw/sch_pcb/SPIEX01.kicad_pcb and its schematic hw/sch_pcb/SPIEX01.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SPIEX01 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).
