Does anyone know if I can make use of this little guy? Particularly the wireless part? (Conveniently on a separate board soldered onto the main board. Also with convenient pads for tiny headers

) Not sure how I could implement this into any projects if it is in fact useful by itself. I've tried googling any schematics with no luck, and it's no big help that the board itself doesn't have any identifying marks.
Any help, as usual, would be greatly appreciated!
