Hello @agilevista6818. The camera package includes the frame that holds the camera, a rechargeable battery, a USB-C charging cable, a long thumbscrew, a quick release buckle, and one each of the flat and curved adhesive mounts.
Most of the accessories/mounts you have for the HERO3 can be used for the HERO7. Well, except for the battery, housing, and mic adapter. But the HERO7 is waterproof on its own up to a depth of 33 feet (10 meters). Hope this helps.
