Questions
How big is the Dobrock69 PCB?
It measures 388 × 126.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Dobrock69 use?
172 parts, built around the XC6206P332MR, ESDAXLC6-1BT2, TS-1187A-B-A-B and NSMD025. 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 Dobrock69 KiCad files?
From the dvorak55/dobrock69 repository on GitHub, at the commit this page was made from: the board is dobrock69.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dobrock69 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).
