Questions

How big is the ADS1299-test circuit PCB?

It measures 100.5 × 95.8 mm and has 2 copper layers, 1.6 mm thick.

What parts does the ADS1299-test circuit use?

109 parts, built around the OPA735AID, REF5025ID and REF5030ID. 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 ADS1299-test circuit KiCad files?

From the IIBM/EEG repository on GitHub, at the commit this page was made from: the board is PCB/ADS1299-test_circuit.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.

Can I use the ADS1299-test circuit design in my own project?

Its repository states no licence, so its author keeps all rights: ask IIBM before reusing the design.
