Peter Gamma from www.petergamma.org doubts about that 2 times 16 channel OpenBCI works satisfyingly for our projects:

Two times 16 channel OpenBCI to get 32 EEG channels?

According to our own little experience most things which can be done have already been tested. And if this would be useful, it would be sold by www.openbci.com themselves. But it is not.

32 channels are offered by mBrainTrain. But who buys EEG devices from mBrainTrain in Serbia?

More than 16 channels are currently not worth it for us personally. But eventually to repair the OpenBCI WIFI shield. Modules which can be repaired can be found on e Bay and Aliexpress.

Medical Computer Systems (MСS) from Russia has shown us an EEG setup with 16 EEG channels which looks very professional:

A new EEG headset with 16 channels – is it based on OpenBCI & can we build this by ourselves if we are skilled enough?

And we think it is worth to exploit OpenBCI to the peak. And Peter Gamma from www.petergamma.org

has reviewed a lot in recent years how to use OpenBCI for physiology. OpenBCI is the most active community in the low-cost high-quality EEG segment. And for more than 16 channels we set our hopes on the final year engineering students from India:

Do develop physiological multi-sensor devices with 32 channels based on InfluxDB.
