Questions
How big is the Dspod cv1800b PCB?
It measures 26.4 × 41.7 mm and has 4 copper layers, 1.53 mm thick.
What parts does the Dspod cv1800b use?
96 parts, built around the TPS62A02DRL, NAU88C22YG, CD4051BE and PMEG2010ER. 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 Dspod cv1800b KiCad files?
From the emeb/dspod repository on GitHub, at the commit this page was made from: the board is dspod_cv1800b/Hardware/dspod_cv1800b.kicad_pcb and its schematic dspod_cv1800b/Hardware/dspod_cv1800b.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dspod cv1800b design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
