Date : 07/16/2013 Model #: SRD531 FCC ID: 2AAJWSRD531 BELWITH PRODUCTS, LLC www.belwith.com 1) Scope of this document : This product specification describes Belwith’s Bluetooth Low Energy module, series number NS- BLE-73720-10-XX. In includes integration information and guidelines to allow a basic understanding of the modules functions, application and includes required documentation that is required to allow the integrator to properly label the OEM device. Caution! Any changes or modifications to this module not approved by Belwith Products LLC could void the authority to operate this module. It contains documentation for proper labeling as required by FCC part 15. This includes documents / labeling that must be applied to the end use host device by the OEM as outlined. Use of this certified transmitter module ( section 15.212 ) can allow the end use host device manufacturer to reduce the testing associated with their product. Additional testing may be required to comply to all other applicable regulations. 2) Basic operation of module NS BLE module contains following: 1. Processor: The NS BLE module is a power-optimized true system-on-chip (SoC) solution for both Bluetooth low energy and proprietary 2.4-GHz applications. The processor combines the excellent performance of a leading RF transceiver with an industry-standard enhanced 8051 MCU, in- system programmable flash memory, 8-KB RAM, and many other powerful supporting features and peripherals. 2. Crystal 16MHz: 16MHz crystal is source of Main Clock freq. of system. It is Ultra Miniature size low profile SMD crystal. This crystal is shielded by metal shield so that it will not export any high frequency from the module. During RF transceiver this clock is enabled. Document Name : NS-BLE-Users Guide Rev.: 01.02 Product Name: NS-BLE-73720-10-XX Page : Page 3 of 18 Mfg: Belwith Products, LLC. Date : 07/16/2013 Model #: SRD531 FCC ID: 2AAJWSRD531 BELWITH PRODUCTS, LLC www.belwith.com Specification: Part 16MHz Crystal Frequency Stability +/-30ppm Frequency Tolerance +/-20ppm Load Capacitance 8pF Motional Resistance(ESR) 80Ohm 3. Crystal 32KHz: 32KHz crystal is the source of Secondary clock freq. of system. It is ultra miniature size low profile SMD crystal. This crystal is shielded by metal shield so that it will not export any high frequency from module. This clock is used for timer, sleep mode, and power saving mode. Specification : Part 32KHz Crystal Frequency Tolerance ±20ppm Load Capacitance 9pF Motional Resistance(ESR) 70 kOhm 4. Impedance Matching Network: Capacitor and Inductor are used for impedance matching between the Antenna and the RF port of the module. 5. Power Supply Pins Information : Pin #8 is VCC and it supply range is between 2.0V-3.6V and Pin #1 and Pin #2 is GND pin of Module. Vcc is given to supply power through pin #8 via LC Filter which is reduced high frequency noise and give stable and noise free power. 6. LC Filter : Ferrite bead and Ceramic capacitors are used in the LC filter. This filter is connected between the power supply pin and the power supply feed point of module. This filter will block high freq. noise in power supply and provide stability against EMI noise.

Date : 07/16/2013 Model #: SRD531 FCC ID: 2AAJWSRD531 BELWITH PRODUCTS, LLC www.belwith.com 7. Metal Shield: CRS Tin shield is used for shielding of processor and crystals. Shield is directly connected to GND plane which will restrict emission of any high freq. that may be generated from the module. Its specification is below: Specification: Surface Area 259.21 mm² Maximum Overall Dimension 16.50 x 16.50 mm Maximum Overall Height 3.60 mm Material Thickness 0.20 mm Weight 0.5 gms Material 0.20 mm CRS Tin 3) Antenna PCB Antenna (Inverted F type) It is a 2.4 GHz PCB antenna. The Inverted F Antenna (IFA) was designed to match an on board impedance. Thus no additional matching components are necessary. Antenna design is configured so as not to attenuate the gain characteristics of the processor. Do not attempt any modifications. 4) Ground Planes Radio requires an RF ground plane on any board made to work with this module. The ground plane should cover the majority of the remaining ( as much as permitted by other components) of the Printed Circuit Board (PCB) area. This can be located on any layer of the PCB. Extend the RF ground plane parallel to module pins 31 and 32 the entire length of the board. Connect all ground pins and do not notch the ground plane around the module. Bottom of module is grounded so be cognizant of vias or conductive traces located under the module that are not soldered masked to prevent shorting. Keep metallic components, connectors, copper traces, internal layers, and ground planes away from the antenna area in 3D space! 5) Frequency Hopping This module uses frequency hopping for data communication with other BLE devices. A pseudo list of no less than 37 available data channels are used and sends data packets utilizing these channels. For advertising, i…

RF Exposure Info

MPE Calculations For RF Exposure Requirements Nordic BLE Module Model: SRD531 Page 1 of 1 MAXIMUM PERMISSIBLE EXPOSURE FOR SUBPART C 2.4 GHz BAND Calculations Power density at the specific separation: S = EIRP / (4R 2 π) S = (1.2618) / (4 * 1 2 * π) S = 0.100411 mW/cm 2 (at 1 cm) Limit = 1 mW/cm 2 where S = Maximum power density (mW/cm 2 ) EIRP = Effective Isotropic Radiated Power (mW) – 1.01 dBm R = distance to the center of the radiation of the antenna (1 cm = limit for MPE) The maximum permissible exposure (MPE) for the general population is 1 mW/cm 2 . The power density at 1 cm does not exceed the 1.0 mW/cm 2 limit. Therefore, the exposure condition is compliant with FCC rules. The EIRP was based on a worst case PEAK value of 96.24 dBuV/m at 3 meters for the EUT. 96.24 dBuV/m @ 3 meters = 1.01 dBm EIRP.
