What is advantage of using Ganglion instead Arduino as sensor signal acquisition board?

What is advantage of using Ganglion instead Arduino as sensor signal acquisition board? Is it precesion? software GUI support?

    Brain signals are very low ~mV. Because of that it is necessary to use amplifier, like ADS1299. Arduino doesn't have that aplifier so it is impossible to measure such low signals. 

    But you can build your own board using ATmega (from Arduino) and ASD1299.

    Thanks for the comments. I can see the case for capturing EEG signals. How about capturing muscle EMG signals?

    EEG is in the microvolt range, say 1 to 80 or so microvolts. EMG / ECG is generally in the millivolt range. So there are some tutorials on arduino acquisition.


    An advantage of OpenBCI is that it is supported by a wide range of signal processing apps.
