AP2 RF Transceiver Module 5 of 19 228 River Avenue, Cochrane, Alberta, Canada T4C 2C1 thisisant.com 1 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.

The table below shows the relationship between the states of the speed select signals and the corresponding baud rates.

The following sample designs show the proper electrical connectivity of an ANT AP2 module to an application microcontroller, using TI MSP430F1232 as example. 1.2.1 Async Mode

AP2 RF Transceiver Module 7 of 19 228 River Avenue, Cochrane, Alberta, Canada T4C 2C1 thisisant.com 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)

8 of 19 AP2 RF Transceiver Module 228 River Avenue, Cochrane, Alberta, Canada T4C 2C1 thisisant.com 1.2.3 Bit Sync Mode Notes: • 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) 1.3 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.

10 of 19 AP2 RF Transceiver Module 228 River Avenue, Cochrane, Alberta, Canada T4C 2C1 thisisant.com 2 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.
