Is it possible to use gopigo3 package software on gopigo2?
I know the hardware is different.
No, these libraries are different from one to another - different hardware asks for different implementations.
Although, there’s one thing you can do. The GoPiGo2 library has a module that can be used as a drop-in replacement and it’s very similar to the GoPiGo3 one. Here it is:
Compare this link I gave you for the GoPiGo2 with the API for the GoPiGo3 and you’ll see they are close to being identical. The difference is again, their implementation and scope.
So if you’ve used so far this module for the GoPiGo2, the transition to the GoPiGo3 should be fast.
Let me know if you’ve got any further questions.
