Questions
How big is the Prometheus PCB?
It measures 223.5 × 222.3 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Prometheus use?
195 parts, built around the TL072CDR-CN, 74LVC2G157DCU, MIC5504-1.8YM5-TR and LTST-C190KGKT. 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 Prometheus KiCad files?
From the wlaub/pcbs repository on GitHub, at the commit this page was made from: the board is PrometheusII/Archive/Rev00/Rev00/prometheus.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Prometheus design in my own project?
Its repository states no licence, so its author keeps all rights: ask wlaub before reusing the design.
