The SM240 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. These low-cost modules can have a range of up to three miles and power consumption as low as 1.6 µA to enable a new generation of batterydriven systems. SNAP’s on-board Python interpreter provides for rapid application development and over-the-air programming, while Atmel’s low-power RF single-chip design saves board space and lowers the overall Bill of Materials and power consumption. The SM240 is approved as an FCC Part 15 unlicensed modular transmitter. The modules provide up to 16 channels of operation in the ISM 2.4GHz frequency band. The SM240 module contains both a power amplifier for transmission and a low noise amplifier in the receive path for extended range.

Recommended Antenna: Figure 1.1 The antenna pattern should be present on the top and bottom layer of the PCB. The antenna patters should be connected by sufficient vias to maintain an impedance of 50 ohms. There should be no plane or trace on the inner layers between the antenna patterns. In the antenna area, there should be no parts in the area between the edge of the ground plane and the edge of the PCB on either side of the PCB. A sample layer stack up which will yield the correct impedance is shown in Table 1.5. The antenna is connected directly to the module by a 50 ohm trace (18.5mil width using stack shown in Table 1.5), and connected by vias to the antenna on the opposite side at the point in Figure 1.1 labeled “To Balun”. Example Gerber files are available. In order to verify the completed design, connect a whip antenna with a known gain, such as a Pulse P/N W1027, to a spectrum analyzer. Verify that the circuit radiates only at the intended frequencies, and that spurious frequencies are below regulatory agency limits. Regulatory certification will require testing at a licensed facility. Production line testing should also include verification, with a spectrum analyzer, that the unit is transmitting only in the intended frequency band.

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. 2. 2.1.1 The system integrator must place an exterior label on the outside of the final product housing the SM240 Modules. Figure 2.1 below shows the contents that must be included in this label. SM240 Modules may only be used with the antenna that has been tested and approved for use with the module. Please refer to the antenna table provided in this section. OEM Labeling Requirements NOTICE: The OEM must make sure that FCC labeling requirements are met. This includes a clearly visible exterior label on the outside of the final product housing that displays the contents shown in Figure 2.1 below. MANUFACTURERS NAME BRAND NAME or TRADE NAME Contains SM240 FCC ID: U9O-SM240 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 interferences, and (2) this device must accept any interference received, including interference that may cause undesired operation. Figure 2.1 FCC Label 2.1.2 FCC Notices WARNING: The SM240 modules have been tested by the FCC for use with other products without further certification (as per FCC Section 2.1091). Changes or modifications to this device not expressly approved by Synapse Wireless Inc. could void the user’s authority to operate the equipment. Model SM240 Data Sheet ©2012 Synapse Wireless, Inc. · · Document Number 430154-01A 500 Discovery Drive, Huntsville, AL 35806 · 256-852-7888 · Page 9 of 12 · synapse-wireless.com WARNING: 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 interferences, and (2) this device must accept any interference received, including interference that may cause undesired operation. NOTICE: OEM’s must certify final end product to comply with unintentional radiators (FCC Section 15.107 and 15.109) before declaring compliance of their final product to Part 15 of the FCC Rules. NOTICE: The SM240 modules have been certified for remote and base radio applications. If the module will be used for portable applications, the device must undergo SAR testing. 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. However, there is no guarantee that interference will not occur in a particular installation. 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. • Consult the dealer or an experienced radio/TV technician for help. 2.1.3 FCC Approved Antennas The SM240 modules are FCC-approved for fixed base station and mobile applications. The FCC requirement for mobile applications states that the antenna must be mounted at least 20 cm (8 in) from nearby persons. Notice: To reduce potential radio interference to other users, the antenna type and its gain should be chosen so that the equivalent isotropically radiated power (e.i.r.p.) is not more than that permitted for successful communication. The SM240 module has been designed to operate with the antennas listed below in Table 2.1. The required antenna impedance is 50 ohms. Table 2.1.

This equipment should be installed and operated with minimum distance 20cm 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. 2.2 Canada (IC) This device complies with Industry Canada license-exempt RSS standard(s). Operation is subject to the following two conditions: (1) this device may not cause interference, and (2) this device must accept any interference, including interference that may cause undesired operation of the device. Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lesser) gain approved for the transmitter by Industry Canada. To reduce potential radio interference to other users, the antenna type and its gain should be so chosen that the equivalent isotropically radiated power (e.i.r.p.) is not more than that necessary for successful communication. Conformément à la réglementation d'Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d'un type et d'un gain maximal (ou inférieur) approuvé pour l'émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à l'établissement d'une communication satisfaisante. This radio transmitter Model: SM240, IC: 7084A-SM240 has been approved by Industry Canada to operate with the antenna types listed below with the maximum permissible gain and required antenna impedance for each antenna type indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device.
