Would be interesting to see which biosensors are known to work with this framework and how they compare. I bought some popular (relatively cheap) device a couple of years ago and I was not convinced it worked at all. A uniform framework would allow to see whether different devices used on the same person provide consistent data.

Edit: just discoverd docs/SupportedBoards.rst :)

What is your experience regarding signal quality for the listed devices?

I guess you mean EEG, right? I dont know good benchmarks to compare signal quality for these devices.. I think the biggest challenge to create such test is a fact that you cannot record data from 2 boards and single person simultaneously and need to collect a lot of data to handle run to run variability

Visually it seems like Unicorn from Gtec and Cyton from OpenBCI are good. But I have no quantitative metrics for it
