Questions
How big is the Mseq PCB?
It measures 135.3 × 78.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mseq use?
93 parts, built around the STM32F413CHU6, SN74HCT125DRE4, CP2102N-A02-GQFN20R and W25Q16JVSSIQ. 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 Mseq KiCad files?
From the MF-Room/mseq_pcb repository on GitHub, at the commit this page was made from: the board is mseq.kicad_pcb and its schematic mseq.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mseq design in my own project?
Its repository publishes it under the CERN-OHL-S-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).
