Overview The  compact designed radio modules contains a powerful ARM7 microcontroller  with  512 kBytes High-Speed Flash, On-chip USB 2.0 Full Speed Transceiver, Ethernet MAC 10/100 base-T in RMII-Mode and an onboard transceiver for 2.4 GHz or 868/915 MHz. The 46 pin interface gives access to most hardware functions of the microcontroller. A long radio transmission range can be achieved by using the coaxial jack (U.FL) version with an external antenna attached. In the Sub-GHz band several hundred meters (100 m = 330  feet)  can  be  reached  without  problems.  The  2.4  GHz  version  is  able  to  cover  up  to     200 m (650 feet) with a ceramic chip antenna.  All versions have a 128-bit AES encryption unit installed. The 512 kB Flash and 128 kB RAM of the deRFarm7 modules provide enough resources to be used for any tasks within a wireless sensor network.  2. Application The main applications for the deRFarm7 radio modules are:   2.4GHz IEEE 802.15.4   868MHz / 915MHz IEEE 802.15.4   ZigBee® Pro   ZigBee® RF4CE   ZigBee® IP   6LoWPAN   Wireless Sensor Networks (WSN)   industrial and home controlling and monitoring   Gateway applications between IEEE 802.15.4 and other networks, e.g. Ethernet

This equipment complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation (FCC 15.19). The internal / external antenna(s) used for this mobile transmitter must provide a separation distance of at least 20 cm from all persons and must not be co-located or oper-ated in conjunction with any other antenna or transmitter.  Installers must  be provided with antenna  installation instructions and  transmitter  operating conditions for satisfying RF exposure compliance. This device is approved as a mobile de-vice with respect to RF exposure compliance, and may only be marketed to OEM installers. Use in portable exposure conditions (FCC 2.1093) requires separate equipment authoriza-tion.  Modifications not expressly approved by this company could void the user's authority to operate this equipment (FCC section 15.21).  This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasona-ble protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful inter-ference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own expense (FCC section 15.105).  11.2.
