Bluetooth is likely an external chip: "Bluetooth 4.0 (external WCN2243); 802.11b/g/n (external AR6003/5, WCN1314)" WiFi is likely as well, but camera support is integrated.

According to some websites this device may also have an FM radio, an accelerometer, a proximity sensor and a compass. I haven't found or discovered those peripherals myself but I know the device has a vibrator which most websites fail to mention. It's not on the list because I haven't physically found it yet.
