I have a pre-assembled brand new Zumo 32U4 Robot and I am very happy with it as it works perfectly, once the necessary software is uploaded.
I tested & work perfectly:
-MazeSolver. With this you must use GridMovement.h /.cpp, but then you must remove them from the Libraries folder, otherwise they will not allow other sketches to work.
Unfortunately Compass DOES NOT WORK: it compliles and loads normally: you even see the LED blinking at the end of upload, but then the robot stays dead and does not do anything.
