Questions

How big is the DAC8822 PCB?

It measures 107.7 × 58 mm and has 2 copper layers, 1.6 mm thick.

What parts does the DAC8822 use?

28 parts, built around the LT1469CS8 and LM7805. 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 DAC8822 KiCad files?

From the Goude63/RPI-Pico repository on GitHub, at the commit this page was made from: the board is programs/DAC8822/pcb/DAC8822.kicad_pcb and its schematic programs/DAC8822/pcb/DAC8822.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the DAC8822 design in my own project?

Its repository states no licence, so its author keeps all rights: ask Goude63 before reusing the design.
