AP2 RF Transceiver Module
ANT™ Overview
ANT™ is a practical wireless sensor network protocol running on 2.4 GHz ISM band. Designed for ultra low
power, ease of use, efficiency and scalability, ANT easily handles peer-to-peer, star, tree and practical
mesh topologies. ANT provides reliable data communications, flexible and adaptive network operation and
cross-talk immunity. ANT’s protocol stack is extremely compact, requiring minimal microcontroller
resources and considerably reducing system costs.
ANT provides carefree handling of the Physical, Network, and Transport OSI layers. In addition, it
incorporates key low-level security features that form the foundation for user-defined, sophisticated,
network-security implementations. ANT ensures adequate user control while considerably lightening
computational burden in providing a simple yet effective wireless networking solution.

ANT AP2 Module
The ANT AP2 module is a drop-in module based on the reference design of nRF24AP2, a new generation of
ANT system on chip family from Nordic Semiconductor. An F antenna is integrated on the small-sized
20mm by 20mm board. The module has been certified to comply with radio regulation or standards
covering global markets include North America, Europe, Japan and Australia. The integrated module eases
the burden for application and system developers from extensive RF and antenna design, and regulatory
compliance testing, allowing quicker time to market. Able to support 8 ANT channels, the module is ideal
to build control or hub nodes of a wireless sensor network.
AP2 modules are currently available in the following varieties.

Application MCU connection
Please refer to “Interfacing with ANT General Purpose Chipsets and Modules” and “nRF24AP2 Product
Specification” section 5 “Host Interface”. The following sample designs show the proper electrical
connectivity of an ANT AP2 module to an application microcontroller, using TI MSP430F1232 as example.

Notes:
•
•
•
Module RXD and TXD connected directly to hardware USART of microcontroller.
Switches on baud rate selection pins (BR1, BR2 and BR3) are for ease of use only. They can be
connected directly to the logic level of interest.
RTS can be connected to an interrupt pin for convenience in some applications. (Interrupt pins
located on Port 1&2 on the MSP430F1232)
1.2.2 Byte Sync Mode
Notes:
•
•
Module SOUT, SIN, and SCLK connected directly to hardware USART of microcontroller.
SEN needs to be on an interrupt capable I/O pin on the microcontroller. (Interrupt pins located
on Port 1&2 on the MSP430F1232)

All interface signals are connected directly to I/O pins on the microcontroller.
SCLK and SEN need to be on an interrupt capable I/O pin on the microcontroller. (Interrupt pins
located on Port 1&2 on the MSP430F1232)
Mounting Guideline
Refer to the recommended footprint drawing in section 4.
It is best to position the AP2 module so that the copper keepout area is on the edge or over hanging the edge of the
mating PCB. If the copper keepout layer is completely within the boundaries of the PCB, the ground plane should not
fully surround the copper keepout. If this is not possible, the copper keepout should be made much larger to prevent RF
degradation. The ground plane is recommended to extend to the full size of the mating PCB, with the exception of the
copper keepout.
To connect to M5IB type of AP2 module, the mating socket is Molex 52991-0208.

Reflow Guideline
Follow the guideline below if AP281M4IB modules go through reflow oven.
Peak solder joint/pad temperatures exceeding 240 ºC are not recommended. If possible, pre-heat the
assembly within the oven profile for ~30 seconds at ~150 ºC . Follow the solder paste manufacturer’s
recommendations, especially regarding temperature ramp rate and the time above liquidus.

Regulatory Approval
(When this revision of document is published, the certification testing is in process and regulatory
approvals are pending.)
The ANT AP2 module has received regulatory approvals for modular devices in the United States (FCC),
Canada (IC), Europe (ETSI), Japan (ARIB), Australia and New Zealand. Such approvals allow the user to
place the module inside a finished product and, in usual case, not require regulatory testing for an
intentional radiator, provided no changes or modifications are made to the module circuitry. This does not
preclude the possibility that some other form of authorization or testing may be required for the finished
product. Changes or modifications could void the user’s authority to operate the equipment. The end user
must comply with all of the instructions provided by the Grantee, which indicate installation and/or
operating conditions necessary for compliance.
2.1
United States
The AP2 module has been tested and found to comply with Part 15 of the FCC interference limits for Class
B devices. Operation is subject to the following two (2) 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.
This equipment generates uses and can radiate radio frequency energy and may cause harmful
interference to radio communications if not installed and used in accordance with the instructions.
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 of the
following measures:
•
•
•
•
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and the receiver.
Connect the equipment into an outlet that is on a different circuit from the receiver.
Consult the dealer or an experienced radio/TV technician for help.
This product does not contain any user-serviceable parts. Unauthorized repairs or modifications could
result in permanent damage to the equipment, and void your warranty and your authority to operate this
device under Part 15 regulations.
The AP2 module is labeled with its own FCC ID, O6R1695 (note: First Character is the letter O, not the #
0.) If the FCC ID is not visible when the module is installed inside another device, then the outside of the
device into which the module is installed must also display a label referring to the enclosed module. This
exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: O6R1695” or
“Contains FCC ID: O6R1695”. Any similar wording that expresses the same meaning may be used.
2.2
Industry Canada Compliance
The AP2 module has been certified for use in Canada under Industry Canada (IC) Radio standards
Specification (RSS) RSS-210 and RSS-Gen. 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.
To comply with Industry Canada regulations, it is required that product containing the AP2 module display
a label referring to the enclosed module. This exterior label can use wording similar to the following:
“Contains IC: 3797A-1695”
This information shall be affixed in such a manner as not to be removable except by destruction or
defacement. The size of the lettering shall be legible without the aid of magnification but is not required
to be larger than 8-point font size. If the device is too small to meet this condition, the information can be
included in the user manual upon agreement with Industry Canada.

Usable band is determined by local regulations
Maximum output power with 0dBm output power setting. Antenna load impedance = 15Ω +j88Ω
Time of maximum Tx only current is typical 300µs and maximum 350µs
Time of maximum current consumption in RX is typical 500µs and maximum 1ms
Transmit only operation provides no ANT channel management across the air channel and is not recommended for
normal operation
Asynchronous serial messages contained two 0 pad bytes, thereby adding to the average current. Values will be
lower without the use of 0 pad bytes
Does not include base current. See current calculation examples below
Value calculated assuming that external 32.768 kHz crystal oscillator is used
Example Current Calculations:
1. Transmit channel with Broadcast data at 4Hz with a bit synchronous serial interface and external source
of 32.768kHZ clock.
I ave
= (I Msg_TR_Bit Sync * Message_Rate) + I Base_32KXO

= (36µA/message * 4messages) + 3.0 µA
= 147 µA
2. Receive channel with Acknowledged data at 2Hz with an asynchronous serial interface at 57600 baud
and internal synthesized 32.768kHZ clock.
I ave
= (I Msg_Ack_Rx_57600 * Message_Rate) + I Base_32kSynt
= (22 µA/message * 2messages) + 100 µA
= 144 µA
