The large square thing with Broadcom on it is more likely a processor for a couple of reasons.
See the gold colored arrow ? That tells the assembler how to orient the chip on the board. You see that same thing with a lot of processors on computer motherboards.
If you take a heat gun and desolder it there are lots of tiny contact points just like on a processor. If i'm breaking down boards i usually group them as: solder in, green fiber, capless processors. Where it takes so much time to break down a board it's probably better not to mess with breaking them down. That's more along the lines of being the refiner's job.
You might try Googling the name & part number. Sometimes it will tell you what it is and even the specific thing it was used for.
