DESCRIPTION
The PacWave™ Bluetooth® Smart module
fully supports single‐mode Bluetooth Low
Energy operation. The module receives its
power from a host that provides 3.3V and
ground to the 6‐pin receptacle, and also
communicates with the host via the UART
on the same 6‐pin receptacle. The two
additional pins provide a wake‐up interrupt
input and a general purpose input/output
(GPIO). The module can be programmed
using the open sockets. The RTC can be
used for timekeeping and scheduling of
activities.

APPLICATION INFORMATION
HOST INTERFACE
The module incorporates one Universal Asynchronous Receiver/Transmitter (UART) interface dedicated to the host for
communication to and from the module. Also available to the host is one General Purpose Input/Output (GPIO) and a
WAKE interrupt input used to wake up the module from a low power sleep mode. The host supplies 1.8V‐3.6VDC and
ground to power the module.
EXTERNAL ANTENNA
The module is certified for use only with the following FCC approved antenna.

FEDERAL COMMUNICATIONS COMMISSION (FCC) STATEMENTS
The PacWave™ Module complies with Part 15 of the United States of America FCC rules and regulations. The Original
Equipment Manufacturer (OEM) must comply with the FCC certification requirements.
15.21 Any changes or modifications made to the module without the manufacturer’s approval could void the user’s
authority to operate the module.
15.105(b) 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.
PLEASE NOTE THE MODULE OPERATION IS SUBJECT TO THE FOLLOWING TWO CONDITIONS:
1. This device may not cause harmful interferences.
2. This device must accept any interference received, including interference that may cause undesired operation.
RADIATION EXPOSURE STATEMENT
This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. End users must
follow the specific operating instructions for satisfying RF exposure compliance. This transmitter must not be co‐located
or operating in conjunction with any other antenna or transmitter, and the end product must have a separation distance
of at least 20mm from all persons. With the documented max output power the module meets the FCC SAR Exemption to
comply with any applicable RF exposure requirements in its final configuration.
ORIGINAL EQUIPMENT MANUFACTURER (OEM) NOTES

The OEM must certify the final end product to comply with unintentional radiators (FCC Sections 15.107 and
15.109) before declaring compliance of the final product to Part 15 of the FCC rules and regulations. Integration
into devices that are directly or indirectly connected to AC lines must add with Class II Permissive Change.

The OEM must comply with the FCC labeling requirements. If the module’s label is not visible when installed,
then an additional permanent label must be applied on the outside of the finished product which states:
“Contains transmitter module FCC ID: ZZOWCM‐01”. Additionally, the following statement should be included
on the label and in the final product’s user manual: “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.”

The module is limited to installation in mobile or fixed applications. Separate approval is required for all other
operating configurations, including portable configuration with respect to Part 2.1093 and different antenna
configurations.

A module or modules can only be used without additional authorizations if they have been tested and granted
under the same intended end‐use operational conditions, including simultaneous transmission operations.
When they have not been tested and granted in this manner, additional testing and/or FCC application filing
may be required. The most straightforward approach to address additional testing conditions is to have the
grantee responsible for the certification of at least one of the modules submit a permissive change application.
When having a module grantee file a permissive change is not practical or feasible, the following guidance
provides some additional options for host manufacturers. Integrations using modules where additional testing
and/or FCC application filing(s) may be required are: (A) a module used in devices requiring additional RF
exposure compliance information (e.g., MPE evaluation or SAR testing); (B) limited and/or split modules not
meeting all of the module requirements; and (C) simultaneous transmissions for independent collocated
transmitters not previously granted together.
This Module is full modular approval, it is limited to OEM installation ONLY.
Integration into devices that are directly or indirectly connected to AC lines must add with Class II Permissive Change.
(OEM) Integrator has to assure compliance of the entire end product incluld the integrated Module.
Additional measurements (15B) and/or equipment authorizations (e.g Verification) may need to be addressed
depending on co-location or simultaneous transmission issues if applicable.
(OEM) Integrator is reminded to assure that these installation instructions will not be made available to the end user
of the final host device.
