Questions
How big is the MegaDAQ PCB?
It measures 138.6 × 100 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MegaDAQ use?
168 parts, built around the MC33079D, TPIC2810D, AMC7812SPAPR and LM78M05CT. 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 MegaDAQ KiCad files?
From the Orthogonal-Systems/MegaDAQ repository on GitHub, at the commit this page was made from: the board is megaDAQ.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the MegaDAQ design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
