Overview The compact designed radio modules contains a powerful ARM™7 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

Radio certification 11.1. United States (FCC) The deRFarm7-15A02, deRFarm7-25A00, deRFarm7-25A02, deRFarm7-15C02, deRFarm7-25C00, deRFarm7-25C02 radio modules comply with the requirements of FCC part 15. The FCC certification of deRFarm7-25A00, deRFarm7-25A02, deRFarm7-15C02, deR-Farm7-25C00, deRFarm7-25C02 radio modules is pending. To fulfill FCC Certification requirements, an OEM manufacturer must comply with the follow-ing regulations: The modular transmitter must be labeled with its own FCC ID number, and, if the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. This exterior label can use wording such as the following. Any similar wording that expresses the same meaning may be used. Sample label for radio module deRFarm7-15A02: FCC-ID: XVV-ARM715A02 This device 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 ac-cept any interference received, including interference that may cause undesired operation. To be used with the deRFarm7-15A02 modules, the external antenna have been tested and approved which is specified in here below. The deRFarm7-15A02 modules may be integrat-ed with other custom design antennas which OEM installer must authorize following the FCC 15.21 requirements. The Original Equipment Manufacturer (OEM) must ensure that the OEM modular transmitter is labeled with its own FCC ID number. This includes a clearly visible label on the outside of the final product enclosure that displays the contents shown below. If the FCC ID is not visi-ble when the equipment is installed inside another device, then the outside of the device into which the equipment is installed must also display a label referring to the enclosed equip-ment. 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.

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. European Union (ETSI) The deRFarm7-15A02, deRFarm7-25A00, and deRFarm7-25A02 modules have been tested compliant for use in European Union countries. If the deRFarm7-15A02, deRFarm7-25A00 and deRFarm7-25A02 modules are incorporated into a product, the manufacturer must ensure compliance of the final product to the European harmonized EMC and low-voltage/safety standards. A Declaration of Conformity must be is-sued for each of these standards and kept on file as described in Annex II of the R&TTE Di-rective. The manufacturer must maintain a copy of the deRFarm7-15A02, deRFarm7-25A00 and deRFarm7-25A02 modules documentation and ensure the final product does not exceed the specified power ratings, antenna specifications, and/or installation requirements as specified in the user manual. If any of these specifications are exceeded in the final product, a submis-sion must be made to a notified body for compliance testing to all required standards. The “CE“ marking must be affixed to a visible location on the OEM product. The CE mark shall consist of the initials "CE" taking the following form: • If the CE marking is reduced or enlarged, the proportions given in the above graduat-ed drawing must be respected. • The CE marking must have a height of at least 5mm except where this is not possible on account of the nature of the apparatus • The CE marking must be affixed visibly, legibly, and indelibly. More detailed information about CE marking requirements you can find at "DIRECTIVE 1999/5/EC OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL" on 9 March 1999 at section 12. 11.3. Approved antennas The deRFarm7-25A00 has an integrated chip antenna. The design is fully compliant with all regulations. The deRFarm7-15A02 has been tested and approved for use with the antenna listed below. The module may be integrated with other custom design antennas which OEM installer must authorize with respective regulatory agencies. The used antenna was connected to the radio module with a 15cm “U.FL-to-SMA pigtail”.
