README
README.mdMOD-DAC
An 8 channel DAC Schematic/PCB project intended for modular use. It should be able to give -5..5 or 0..5 or some other range within that. It is intended to be driven by 3.3v signals from a micro controller, not included in this project.

Questions
How big is the Mod dac PCB?
It measures 44.2 × 59.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Mod dac use?
71 parts. 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 Mod dac KiCad files?
From the x37v/mod-dac repository on GitHub, at the commit this page was made from: the board is mod-dac.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Mod dac design in my own project?
Its repository states no licence, so its author keeps all rights: ask x37v before reusing the design.
