Questions
How big is the SIGMAGE PCB?
It measures 270 × 170 mm and has 6 copper layers, 1.6 mm thick.
What parts does the SIGMAGE use?
725 parts, built around the OPA1612AIDRGR, EC11E183440C, PCM1803ADB and MAX8902BATA/V+T. 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 SIGMAGE KiCad files?
From the allogic/SIGMAGE repository on GitHub, at the commit this page was made from: the board is SIGMAGE_HW/SIGMAGE/SIGMAGE.kicad_pcb and its schematic SIGMAGE_HW/SIGMAGE/ADC.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SIGMAGE design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
