Fire TV Stick 3 & Stick Lite share the same model number and are the same size as the Fire TV Stick 2
If there was any doubt that the 3rd-gen Fire TV Stick and the 1st-gen Fire TV Stick Lite share the exact same hardware, the fact that they both use the same model number of S3L46N and the same FCC ID of 2AUQI-7436 should put that to rest.
