Questions
How big is the BioZ front end V2 1 PCB?
It measures 262.5 × 120.1 mm and has 4 copper layers, 1.6 mm thick.
What parts does the BioZ front end V2 1 use?
362 parts, built around the TEC 3-0911, AD8250ARM, THS4631D and THS4151IDGK. 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 BioZ front end V2 1 KiCad files?
From the Neuro-Interface-Lab/BIMMS repository on GitHub, at the commit this page was made from: the board is Hardware/KiCAD/BioZ_front_end_V2_1/BioZ_front_end_V2_1.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the BioZ front end V2 1 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Neuro-Interface-Lab before reusing the design.
