Why does Raspberry Pi not need to conform to the new "standards" of the FCC that require locking down firmware in routers? If it has onboard wifi, and you can turn it into a router... what's the difference between someone installing OpenWRT on a raspi vs. installing OpenWRT on a TPLink? edit: This is a legitimate question, not an opinion.

The FCC was mostly concerned about DFS in that case, which only applies to the 5GHz spectrum, and is only applied by the AP in a wireless network.

Note that if you have a 5GHz wifi dongle, you'll see that the Linux regulatory framework will disallow running it in AP mode for this reason - almost all lack DFS.

I couldn't spot the typical wavy PCB antenna pattern anywhere. Is that small cube in the upper left corner of external top view a ceramic antenna? Looks to me like the 2 LEDs have been shifted further down towards lower left and replaced with something new. Update: Just noticed the radio testing report says single PCB mounted chip ceramic. I still can't spot it with certainty.

Yes, this is the antenna. I cant believe it took them that long, Broadcom is famous for their BT/Wifi chips, buildin wifi was a no brainer, and cost shouldnt be an issue when you have great connections inside the company.

From their blog posts and forum discussions, I have the impression BC was not exactly enthusiastic about the Pi to start with, but got convinced only after Pi v1 become a hit. Perhaps there is still some reluctance and resistance inside BC? After all, they did take ~3 years to upgrade from ARMv6 to ARMv7 while all the other SBCs were already using ARMv7 cores much earlier.

Also, good on the Pi Foundation for keeping this listing in the open rather than requesting 6 month confidentiality for the pictures/test report (which almost all companies do).

I don't think they did: the confidentiality period is now 45 days only by default, see http://acbcert.com/documents/misc-docs/Memo-Short-Term-Vs-St...

Certification took place at Track (now Element UK) on 2015-11-23, given the external picture dates, or 95 days ago, so it looks like it has been extended once.

Is a ceramic wifi antenna's range comparable to that of a regular PCB antenna?

Given Broadcom's connections to the project, it's almost a surprise they didn't have some kind of Broadcom option for WiFi/BT earlier. Must have stung at Broadcom to be powering the most popular hobbyist ARM Linux board, but almost every one using WiFi powered by Realtek,Ralink,etc.

It'll be interesting, given the state of Broadcom wifi drivers on linux.

It looks like the ceramic antenna is the light brown SMT between the DSi connector and the upper left hole in the top view pictures.

Are you sure that's the antenna? It looks more like it'd be a balun. It even has what looks like a feed line going to the keepout that's right next to it. I feel like the one in the picture is missing the actual antenna.

The onboard Wifi and Bluetooth really makes the barrier of entry for IoT $5 (assuming the stick with the $5 mark)

As the other poster mentioned, they've typically been $35. The barrier of entry for IoT is still pretty low though, you can get an ESP8266 for ~$2/ea. That'll handle wifi and can also be your application processor. For another ~$2-3 you could add on a BLE module too.

ESP32 is coming with both Wi-Fi and BLE: http://espressif.com/products/hardware/esp32/overview
