It is currently not possible to get more than 16 channels with the OpenBCI architecture

“is not currently possible to get 24 channels with the Cyton architecture. This is because ALL channels must be sampled at the exact same moment, under control of the microprocessor on the Cyton board. This cannot be done with TWO Cyton boards. “

But it is possible to do some experiments. Especially with PiEEG:

Therefore write to Rak Ildar Rakhmatulin to bring PiEEG back. Ildar’s e-mail can be found under the tag “PiEEG”:
