Questions
How big is the Cluster PCB?
It measures 35 × 45.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Cluster use?
17 parts, built around the BSS84. 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 Cluster KiCad files?
From the cinnamondev/yadh2 repository on GitHub, at the commit this page was made from: the board is finger_cluster/cluster.kicad_pcb and its schematic finger_cluster/cluster.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Cluster 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).
