Questions
How big is the Pi pico dds PCB?
It measures 43.2 × 36.8 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Pi pico dds use?
77 parts, built around the RP2040, OPA2192ID and W25Q32JVZPIQ. 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 Pi pico dds KiCad files?
From the gabeak2/RP2040_PIO_DAC repository on GitHub, at the commit this page was made from: the board is pi_pico_dds.kicad_pcb and its schematic pi_pico_dds.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Pi pico dds design in my own project?
Its repository states no licence, so its author keeps all rights: ask gabeak2 before reusing the design.
