Internal details
Figure 3 is a shot of the N+ main board. Like the Belkin N, the N+ uses Ralink's RT2880 Processor / MAC / BB SoC combined with a Ralink RT2820 2T3R 2.4 GHz Transceiver. The WAN and LAN ports are provided by a Realtek RTL8366SR gigabit switch.
Even though Belkin doesn't spec jumbo frame support, I ran a quick test on the switch and found that it passed 4K jumbo frames. (The switch chip is spec'd up to 9K frames.) I don't know for sure what the chip at the upper left in the photo is, but my guess is that it's a USB interface.
Figure 3: N+ Main board
I partially opened the cover to get a better view of the components, but found that the FCC ID photo (Figure 4) really did represent production product. The big ol' foil shield isn't very pretty, but is probably providing some RF shielding for the Realtek switch and some cheap heat sinking, too!

Figure 5 shows the companion Belkin N+ Wireless USB Network Adapter (F5D8055 v1) board that Belkin sent along for the ride. This FCC photo very clearly shows a Ralink RT2870 USB BB/MAC and the same RT2820 Transceiver used in the router.
