SNAP Engine SM220 Modules Overview The SNAP Engine Model SM220 series currently consists of the SM220UF1. 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 SM220 embeds Synapse’s SNAP OS, the industry’s first Internet-enabled, wireless mesh network operating system, into the Atmel ATmega128RFA1 single-chip AVR® microcontroller with an integrated transceiver that delivers up to 2Mbits/sec.

Mechanical Drawings Figure 1 and Figure 2 show the modules with the compact F antenna ad U.FL Connector options. NOTE: The area under the module's antenna (marked KEEP OUT AREA) should have no components, no traces, and no copper on any layer of the printed circuit board. 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.
D Figure 2: Block diagram showing the major subsystems comprising Model SM220 R Selecting an Antenna T AF er en G The SM220 uses the internal 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. This is a one-time change that will persist through reboots and program changes. To revert to the internal antenna, change bit 0x0010 of NV ID 64 back to 0.

• • Cleaning with alcohol or a similar organic solvent will likely flood soldering flux residuals into the two housings, which is not accessible for post-washing inspection. The solvent could also damage any stickers or labels. Ultrasonic cleaning could damage the module permanently. The recommended approach is to consider using a “no clean” soldering paste and eliminate the post-soldering cleaning step. Repeating Reflow Soldering Only a single reflow soldering process is encouraged for host boards.
Agency Certifications United States (FCC) The Model SM220 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 SM220 Modules.
NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
