This part supports single mode, Bluetooth® Smart applications. Three LEDs are incorporated (Green, Yellow and Red) and are driven by the CSR1010 SOC. An SPI serial interface plus one GPIO is made available at the interface connector J1. The supply voltage also comes from J1. The circuit is fabricated with a two layer PCB, and has a shield over all of the RF components (except the antenna). This module includes an integrated helical trace antenna (printed on both sides).

This is preferred to allow the LEDs to be visible, and keeps the antenna located behind an opening or plastic material to allow for good RF emission. The module has a single connector (J1) that allows for board-to-board interfacing or for using a cable to another board. The mating connector (through hole type) is listed in the following table. Table 2-5 – BTM Mating Connectors Mating Connector Type Manufacturer Part No. Board-to-Board Connector JST 08JQ-ST Inline Connector JST XHP-8 A plastic enclosure is recommended for best RF range. If using a metal enclosure, the antenna should be kept clear of metal for at least 1.5 inches in all directions, if possible. Nylon standoffs and fasteners are recommended for mounting the module to the housing. 3 Agency Certifications 3.1 United States (FCC) The Model 28170 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 28170 BTM Module. Figure 3-1 below shows the contents that must be included in this label. 2. 28170 BTM Modules may only be used with the antenna that has been tested and approved for use with this module. 3.1.1 OEM Labeling Requirements NOTE: 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 3-1 below.

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. Figure 3-1 – FCC Label NOTE: If the device is smaller than the palm of your hand and this will not fit on a label, the last line is allowed to go into the user’s manual instead. 3.1.2 FCC Notices WARNING: The 28170 modules have been tested by the FCC for use with other products without further certification (as per FCC Section 2.1091). Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. NOTE: OEM's must verify 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. NOTE: The 28170 modules have been certified for remote and base radio applications. If the module will be used for portable applications, the device must undergo the applicable SAR testing. 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. 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
Document: User's Manual Title: Last Saved: 28170 Bluetooth® LE Module 8/19/2016 5:22:00 PM Page 9 of 10 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. NOTE: The preceding statement must be included as a CAUTION statement in OEM product manuals, in order to alert users of FCC RF Exposure compliance. NOTE: This transmitter must not be co-located with any other transmitters except in accordance with FCC multi-transmitter product procedures NOTE: This filing meets the SAR threshold exclusion set forth in KDB 447498 and therefore can be used in mobile/portable configurations. 3.1.3 FCC Approved Antennas The 28170 RF 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. Only the provided, permanently attached, PCB trace type antenna is approved for use. The 28170 module does not include any other antenna option. 3.2 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. For this device, the only antenna option is a permanently attached, PCB trace type, and does not include any other antenna option.

Pour cet appareil, la seule option de l'antenne est un type de trace PCB fixé de façon permanente, et ne comprennent pas toute autre option d'antenne. 3.2.1 OEM Labeling Requirements Labeling requirements for Industry Canada are similar to those of the FCC. A clearly visible label on the outside of the final product housing must display the contents shown in Figure 3-2 below. MANUFACTURERS NAME BRAND NAME or TRADE NAME MODEL: Contains IC: nnnnn-28170 Figure 3-2 – IC Label NOTE: The OEM can choose to implement a single label combined for both FCC and IC labeling requirements. If a combined single label is chosen, there must be a clearly visible label on the outside of the final product housing displaying the contents shown in Figure 3-3 below. MANUFACTURERS NAME BRAND NAME or TRADE NAME Contains FCC ID: OBH-28170 Contains IC: nnnnn-28170 This device complies with part 15 of the FCC Rules.
