Questions
How big is the Avalon communication board PCB?
It measures 100 × 62.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Avalon communication board use?
116 parts, built around the ESP-12S, LMH6643MM, LM2575S-5.0 and LM2576WT. 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 Avalon communication board KiCad files?
From the AvalonROV/Electrical_2018 repository on GitHub, at the commit this page was made from: the board is Hardware/Communication Board/avalon_communication_board.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Avalon communication board design in my own project?
Its repository states no licence, so its author keeps all rights: ask AvalonROV before reusing the design.
