2400 to 2483.5 MHz
LC Filter
BC5MMRPA is a Class 2 Bluetooth sub-system using BlueCore5 –Multimedia ROM chipset from leading Bluetooth chipset
supplier Cambrige Silicon Radio. .It interfaces to a 32-kbit EEPROM using I2C interface. The software stack running on the
BlueCore5 ROM chipset is fully compliant to Bluetooth Specification v2.1 + EDR. BC5MMRPA also has necessary balun and
bandpass filters to interface with a build-in PCB antenna, which forms a very cost effective radio subsystem.

authorization to operate this equipment.
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.
Radiofrequency radiation exposure Information:
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. Please see the
RF Exposure information. This transmitter must not be co-located or operating in conjunction with any other antenna or
transmitter.
This device should be installed and operated with a minimum distance of 20 cm between the antenna and all persons.
