Hi,

Robert Lawson (robert at sherab.net) wrote about FreeEEG32 and LSL:"I'm 
talking to the developer about adding LSL. I predict we'll have it in 
less than 2 weeks".

I found a youtube demo for the FreeEEG32:

250 USD for a 32 channel EEG device with LSL support, this is an 
interesting new option. I found the following data:

Max Programmable Gain Amplification (PGA) FreeEEG32: 8x

Max Programmable Gain Amplification (PGA) OpenBCI: 24x

The FreeEEG32 combines four 8-channel AD7771 ADCs, and does not use the 
expensive ADS1299 chips which OpenBCI uses. Does this affect the signal 
quality, and is the FreeEEG32 a research grade device?

Regards,

Peter
