Overview
SteDAC is an open-source printed circuit board by stefantquach, from the stefantquach/steDAC repository on GitHub. It is a 2-layer board of 100 × 80 mm with 164 parts on 155 nets, routed with 988 tracks and 112 vias.
It is built around the ATSAMS70N20A-AN, OPA1612AID and ES9038Q2M, with the NCP161ASN330T1G-HXY, ADP7182ACPZN-R7 and MAX38902AATA+T among its other parts. Its parts include 79 capacitors, 36 resistors, 13 ICs, 5 connectors and 2 diodes. It belongs with the SAM D and SAM boards of this library.

Questions
How big is the SteDAC PCB?
It measures 100 × 80 mm and has 2 copper layers, 1.6 mm thick.
What parts does the SteDAC use?
164 parts, built around the ATSAMS70N20A-AN, OPA1612AID, ES9038Q2M and NCP161ASN330T1G-HXY. 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 SteDAC KiCad files?
From the stefantquach/steDAC repository on GitHub, at the commit this page was made from: the board is KiCAD/steDAC.kicad_pcb and its schematic KiCAD/AK4493_sch.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the SteDAC design in my own project?
Its repository states no licence, so its author keeps all rights: ask stefantquach before reusing the design.
