What is the reason for using the Cyton board in the example projects ? Why not Gangiion ?
Generally the example projects each only involve a few electrodes, so are adaptable to either board. The 'Getting Started' pages cover more tutorial material per board. In the case of EMG, the page shows both Cyton and Ganglion configurations.
Differentiating every Doc for both Cyton and Ganglion decreases readability and increases complexity. If you think a specific document should include instructions for Ganglion also, you can make an issue on the Docs Github: https://github.com/OpenBCI/Documentation/issues
Thanks for asking this question!
