SNAP Engine RF220UF1 Modules Overview The SNAP Engine Model RF220UF1 series consists of an SM220UF1 on a carrier board. It is an IEEE 802.15.4, low-power, highly reliable solution for embedded wireless control and monitoring networks that require high data rates. The Model RF220UF1 embeds Synapse’s SNAP OS, the industry’s first Internet-enabled, wireless mesh network operating system, into the Atmel ATmega128RFA1 singlechip AVR® microcontroller with an integrated transceiver that delivers up to 2Mbits/sec.
• 4K internal EEPROM • 6 PWM outputs • Supports over the air firmware upgrades. (This process is further defined in the Portal User Guide.)

Mechanical Drawings RF220UF1 Mechanical Drawing on page 6 and Block diagram showing the major subsystems comprising Model RF220UF1 on page 7 are for modules with the compact F antenna and U.FL Connector options. NOTE: For best performance, the module should be mounted on the outside edge of the circuit board with the antenna side as close to the edge of the board as possible. Figure 1.
Figure 1.2: Block diagram showing the major subsystems comprising Model RF220UF1 Selecting an Antenna The RF220UF1 uses the on-board compact F antenna by default. If you wish to use an external U.FL antenna with your application, you will need to set bit 0x0010 of NV ID 64 to 1 and reboot your node. This is a one-time change that will persist through reboots and program changes. To revert to the on-board antenna, change bit 0x0010 of NV ID 64 back to 0 and reboot the node.

Agency Certifications United States (FCC) The Model RF220 modules comply with Part 15 of the FCC rules and regulations. Compliance with the labeling requirements, FCC notices, and antenna usage guidelines is required. In order to comply with FCC Certification requirements, the Original Equipment Manufacturer (OEM) must fulfill the following requirements. 1. The system integrator must place an exterior label on the outside of the final product housing the RF220 Modules.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures: • Reorient or relocate the receiving antenna. • Increase the separation between the equipment and receiver. • Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
WARNING: RF Exposure: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20 cm between the radiator and your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. NOTICE: The preceding statement must be included as a CAUTION statement in OEM product manuals in order to alert users of FCC RF exposure compliance.
