Questions
How big is the DSSEM PCB v02 PCB?
It measures 95.5 × 70 mm and has 4 copper layers, 1.6 mm thick.
What parts does the DSSEM PCB v02 use?
134 parts, built around the BH1750FVI-TR, LTR-390UV-01, BC660K-GL and BQ25798RQMR. 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 DSSEM PCB v02 KiCad files?
From the steinerdomajz/DSSEM repository on GitHub, at the commit this page was made from: the board is hardware/source/DSSEM_PCB_v02.kicad_pcb and its schematic hardware/source/DSSEM_PCB_v02.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DSSEM PCB v02 design in my own project?
Its repository states no licence, so its author keeps all rights: ask steinerdomajz before reusing the design.
