Questions
How big is the LASDAC PCB?
It measures 93.7 × 70 mm and has 2 copper layers, 1.6 mm thick.
What parts does the LASDAC use?
89 parts, built around the DAC084S085CIMM, LM358 and SPX431LS-L. 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 LASDAC KiCad files?
From the Grix/LASDAC repository on GitHub, at the commit this page was made from: the board is PCB/LASDAC.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the LASDAC design in my own project?
Its repository states no licence, so its author keeps all rights: ask Grix before reusing the design.
