Well unfortunately I don’t know much about it. Fundamentally I don’t think there is that much difference. Don’t quote me on this, but I’m pretty sure that the GoPiGo1 is compatible with the GoPiGo2 software wise. Also in case you didn’t know the GoPiGo3 is out now. Which the GoPiGo3 was resigned software wise. Hardware changes, yes. Mostly the changes were software though.
