Questions
How big is the Dobo Phase3 PCB?
It measures 90.2 × 95.9 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Dobo Phase3 use?
187 parts, built around the LMH6505MA, LMH6624MF and AD8361ARM. 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 Dobo Phase3 KiCad files?
From the SlugSat/Schematics_PCBs repository on GitHub, at the commit this page was made from: the board is LT/Integration/Final Integration Layouts/Phase 3/DoBo/Dobo_Phase3/Dobo_Phase3.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Dobo Phase3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask SlugSat before reusing the design.
