My nybble servo number 12 suddenly stopped working yesterday. There seems to be no problem with the servo itself. Because when I plug the servo into the 8th connector, the servo moves. Probably the problem occurred on the NyBoard side. When I connect the servo to connector number 12, it stops working. In this case, does my NyBoard need repair? Is there any way to repair it by myself? Or is there any other good solution?
