Questions
What parts does the Old.A1 - Analogue Board use?
277 parts, built around the OPA2182ID, AD7190BRUZ, OPA140AID and 74HC138. 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 Old.A1 - Analogue Board KiCad files?
From the DumberThanUsual/DSMU repository on GitHub, at the commit this page was made from: the board is PCB/A1 - Analogue Board/old.A1 - Analogue Board.kicad_pcb and its schematic PCB/A1 - Analogue Board/A1 - Analogue Board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Old.A1 - Analogue Board design in my own project?
Its repository states no licence, so its author keeps all rights: ask DumberThanUsual before reusing the design.
