Questions
How big is the Ebus adapter PCB?
It measures 100 × 50 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Ebus adapter use?
32 parts, built around the ADUM1201AR, LM7805CT, LM78L05ACZ and BC547. 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 Ebus adapter KiCad files?
From the sarfata/ebus-adapter repository on GitHub, at the commit this page was made from: the board is EBusAdapter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ebus adapter design in my own project?
Its repository states no licence, so its author keeps all rights: ask sarfata before reusing the design.
