Questions
How big is the Spidriver1 PCB?
It measures 61.8 × 48.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Spidriver1 use?
21 parts, built around the EFM8BB10F8G-A-QFN20, FT230XQ-R and ZXCT1110W5. 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 Spidriver1 KiCad files?
From the jamesbowman/spidriver repository on GitHub, at the commit this page was made from: the board is hardware/spidriver1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Spidriver1 design in my own project?
Its repository publishes it under the BSD-3-Clause licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
