I love seeing fun projects like this, but from what I can see in photos and the GitHub profile I think this would be more appropriate as an open-source hobby project than a $240 commercial product without schematics available.
The board is a minimal implementation of the ADS1299 chip, which is a highly integrated part for EEG measurements. The chip can be purchased for $50 or less in single quantities and your average electronics hobbyist could put together a basic Arduino Shield PCB around it in a weekend. It's a great chip. However, dealing with all of the complexities of low-level measurements is challenging. Getting good, clean signals and managing interference is a complex topic.
The GitHub repo has a lot of empty 'readme.txt' files and scraps of Python scripts, but the manual and documentation are both empty.
It can be wired to an Arduino if you like and it has every possible function of the EEG chip exposed. It also has a much more robust layout and more flexible connections. Getting good measurements of low voltage signals with a 24-bit ADC is complicated, so it's important to have a well designed, tested, and documented solution to use.

If anyone wants to play with this EEG chip, you can buy the entire professionally-designed evaluation board with a companion USB motherboard for $240 (the price of this Arduino shield): https://www.digikey.com/en/products/detail/texas-instruments...
