Questions
How big is the Ephys test board PCB?
It measures 150 × 120 mm and has 4 copper layers, 1.58 mm thick.
What parts does the Ephys test board use?
567 parts, built around the SC0914(13), AD5683RARMZ, MAX4489AUA+ and W25Q128JVSIQ. 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 Ephys test board KiCad files?
From the open-ephys/ephys-test-board repository on GitHub, at the commit this page was made from: the board is pcb/ephys-test-board.kicad_pcb and its schematic pcb/ephys-test-board.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Ephys test board design in my own project?
Its repository states no licence, so its author keeps all rights: ask open-ephys before reusing the design.
