of 19 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.
AP2 RF Transceiver Module 1 5 of 19 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.
of 19 AP2 RF Transceiver Module The baud rate of the asynchronous communication is controlled by the speed select signals BR1, BR2 and BR3. The table below shows the relationship between the states of the speed select signals and the corresponding baud rates. 1.
AP2 RF Transceiver Module 7 of 19 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.
of 19 AP2 RF Transceiver Module 1.2.3 Bit Sync Mode Notes: • • 1.3 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.
AP2 RF Transceiver Module 1.4 9 of 19 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. 228 River Avenue, Cochrane, Alberta, Canada T4C 2C1 thisisant.
