LM072 Class 1 Bluetooth Serial Data Module Product: LM072 Part No: 072-0125 for BT2.0 F/W Part No: 072-0110 for BT2.1 F/W Datasheet Rev1.2/11-07-12 1 General Description LM072 is LM Technologies Ltd Class 1 Bluetooth Data module with external antenna. This module is a CSR Bluecore 4 (BC04) chip based surface mount module available with Bluetooth Serial Port Prole (SPP) rmware. This module is ideal for adding long range wireless connectivity to embedded products. The module acts as a standalone unit (i.e. it does not need a host to drive it) and can interface with embedded microcontrollers via UART. It operates over a voltage range of 3.0 V to 3.6 V and gives excellent performance over a distance of 70-100 m with external antenna. This is a tried and tested module also used in other LM best selling products like LM048 and LM058 serial adapter as well as LM400 and LM410 Data Modules.

(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation. NOTE 1: 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 o 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 dierent from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help. NOTE 2: Any changes or modications to this unit not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. 11 FCC Radiation Exposure Statement This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must follow the specic operating instructions for satisfying RF exposure compliance. Note 1: This module certied that complies with RF exposure requirment under portable or mobile or xed condition, this module is to be installed only in portable or mobile or xed applications. A portable device is dened as a transmitting device designed to be used so that the radiating structure(s) of the device is/are within 20 centimeters of the body of the user A mobile device is dened as a transmitting device designed to be used in other than xed locations and to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter's radiating structure(s) and the body of the user or nearby persons. Transmitting devices designed to be used by consumers or workers that can be easily re-located, such as wireless devices associated with a personal computer, are considered to be mobile devices if they meet the 20 centimeter separation requirement. A xed device is dened as a device is physically secured at one location and is not able to be easily moved to another location. Note 2: Any modications made to the module will void the Grant of Certication, this module is limited to OEM installation only and must not be sold to end-users, end-user has no manual instructions to remove or install the device, only software or operating procedure shall be placed in the end-user operating manual of nal products. Note 3: The device must not transmit simultaneously with any other antenna or transmitter. LM072 Page 6 of 7

For example, if a host was previously authorized as an unintentional radiator under the Declaration of Conformity procedure without a transmitter certied module and a module is added, the host manufacturer is responsible for ensuring that the after the module is installed and operational the host continues to be compliant with the Part 15B unintentional radiator requirements. Since this may depend on the details of how the module is integrated with the host, LM Technologies Ltd shall provide guidance to the host manufacturer for compliance with the Part 15B requirements. Note 5: FCC ID label on the nal system must be labeled with Contains FCC ID: VVXLM072 or Contains transmitter module FCC ID: VVXLM072. The transmitter module must be installed and used in strict accordance with the manufacturer's instructions as described in the user documentation that comes with the host product. LM Technologies Ltd is responsible for the compliance of the module in all nal hosts. 12 Revision History Revision Rev1.0 Rev1.1 Date 17/12/2010 03/07/2012 Rev1.2 11/07/2012 Comments First Version 1.
