Animated armature only to Unity

The idea is to export an armature only that I have animated in Blender to serve as a sprite based animation in Unity.
I know there is a program spriter and it has a spriter2unity package but it does have issues they say and I’m not sure of the licence etc etc.
So, is there a way to export the animated bones only? So in Unity I just parent my sprites under them and be happy with the results? (Or do I have to animate planes with my sprites as textures on them?)
Thanks in advance.
