Questions
How big is the Schematic Backup 9 PCB?
It measures 160 × 136.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Schematic Backup 9 use?
140 parts, built around the AD8675AR, AD8676BR, AD5781BRU and LT1963AEQ. 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 Schematic Backup 9 KiCad files?
From the PickyPointer/SrE repository on GitHub, at the commit this page was made from: the board is DACs/KiCad Design/Schematic PCB Backups/Schematic Backup 9.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Schematic Backup 9 design in my own project?
Its repository states no licence, so its author keeps all rights: ask PickyPointer before reusing the design.
