Questions
How big is the EBH-10 PCB?
It measures 38.4 × 20.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EBH-10 use?
49 parts, built around the BZT52C4V7T. 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 EBH-10 KiCad files?
From the maholli/EHB repository on GitHub, at the commit this page was made from: the board is EHB-10/EBH-10.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EBH-10 design in my own project?
Its repository states no licence, so its author keeps all rights: ask maholli before reusing the design.
