IRIS OEM Edition Hardware Reference Manual 4 IRIS OEM Reference Board The IRIS OEM reference board is a carrier PCB with the same form factor and functionality as the IRIS family product. It consists of a surface mount module consisting of a processor core and a two-way radio, high density digital interface connector, RF coaxial antenna connector, power supply connection, battery pack connection, power switch, and mounting holes. 4.
IRIS OEM Edition Hardware Reference Manual The RF output port is 50 ohm and can be connected directly to a 50 ohm microstrip or 50 ohm coaxial cable. A PI-Matching network is recommended for antenna matching especially when using inner antennas. If the antenna’s input impedance is not 50 ohm, please contact antenna vendor and ask for matching network value. An example of a typical layout is shown in Figure 4-2. OEM Module OEM Module Figure 4-2. An example layout for OEM Edition Module 4.
IRIS OEM Edition Hardware Reference Manual When CKOPT is programmed, the Oscillator output will oscillate will a full rail-to-rail swing on the output. This mode is suitable when operating in a very noisy environment or when the output from XTAL2 drives a second clock buffer. This mode has a wide frequency range. When CKOPT is unprogrammed, the Oscillator has a smaller output swing. This reduces power consumption considerably.

Internal Calibrated RC Oscillator Operating Modes CKSEL[3..0] Nominal Freq Range (MHz) 0010 7.3 – 8.1 4.3.2 System Clock Prescaler The processor has a system clock prescaler, and the system clock can be divided by setting the “Clock Prescale Register - CLKPR” as shown in Table 4-4. This feature can be used to reduce the system frequency and the power consumption when the requirement for processing power is minimized. Table 4-4.
IRIS OEM Edition Hardware Reference Manual 2) Apply a small amount of flux to the tinned pads. 3) Place the OEM module on the pads, making sure to have the pin one reference markings aligned. Inspect the placement to make sure the OEM module edge contacts are centered on the pads on all four sides. 4) While applying mild pressure to the top of the OEM module (to hold it in position), apply heat from a fine soldering tip to the area of the pre-tinned pad that is exposed at the edge of the OEM module.
IRIS OEM Edition Hardware Reference Manual 4.5 Peripheral Interfaces on OEM Edition Module The ports available on the OEM Edition module consist of the following: • • • • • • • UART0 USART1 I2C bus SPI bus ONE-WIRE ADC ports GPIO 4.5.1 UART0 The UART0 port is a dual function port. It is used in conjunction with the RSTN (active LOW) and SPI_CK lines to program the CPU. The CPU is in program mode if the RSTN line is low, and data is clocked in using the UART0_RX and SPI_CK lines.

IRIS OEM Edition Hardware Reference Manual single ended voltage inputs are reference to 0V (GND). The ADC ports are high impedance inputs to the ADC, used for voltage sampling. The uppermost bits (ADC[4..7]) also support the JTAG interface. The JTAG port can be enabled by choosing that option in the fuse bits for the processor. Choosing the JTAG active option will cause approximately 50k ohms to be applied from the ADC pin to VCC. This setting can affect the accuracy of ADC readings from weak sources.
IRIS OEM Edition Hardware Reference Manual 5 Power 5.1 Battery Power M2110 is designed for battery power. Any battery combination (AA, AAA, C, D, etc., cells) can be used provided that the output is between 2.7 VDC to 3.6 VDC. Care should be used in selecting the battery and its capacity to match the energy needs of the motes and their required operating span. Also make sure that the temperature range and associated capacity degradation are looked at prior to deployment.

IRIS OEM Edition Hardware Reference Manual 6 Radios 6.1 M2110 The radio used by the M2110 is an IEEE 802.15.4 compliant RF transceiver designed for lowpower and low-voltage wireless applications. It uses Atmel’s AT86RF230 radio that employs OQPSK (“Offset Quadrature Phase Shift Keying”) with half sine pulse shaping. The 802.15.4 radio includes a DSSS (digital direct sequence spread spectrum) baseband modem providing a spreading gain of 9 dB and an effective data rate of 250 kbps.
IRIS OEM Edition Hardware Reference Manual 7 Antennas 7.1 Radio/Antenna Considerations An antenna facilitates the transfer the reception of RF energy to and from free space. Care should be taken in the antenna choice or design so it provides proper coverage for the environment expected. Good antenna design is the most critical factor in obtaining good range and stable throughput in a wireless application.

IRIS OEM Edition Hardware Reference Manual The OEM Edition module is well suited for embedded antenna designs. Proper care must be taken in the design phase to account for packaging effects due to the enclosure, metallic parts adjacent to the antenna, and placement on the PCB. In addition, the final application and expected performance should be evaluated for suitable antenna choice. For an example of embedded antenna design, Refer to the application note on “Antenna Design Considerations”. Doc.
IRIS OEM Edition Hardware Reference Manual 8 Flash Data Logger and Serial ID Chip All OEM Edition Modules feature a 512 k serial flash for storing data, measurements, and other user-defined information. It is connected to one of the USART on the ATmega1281V. This chip is supported in MoteWorks which uses this chip as micro file system. The serial flash device supports over 100,000 measurement readings. This chip is also used for XOtap (Over the Air Programming) services available in MoteWorks.
IRIS OEM Edition Hardware Reference Manual 9 Atmega1281 Fuses The ATMega1281V processor on the OEM edition modules has many programmable fuses to control various parameters. Refer to Atmel’s technical information for the ATMega1281V for a complete discussion of the fuses. There are two fuses that MoteWorks users should be aware of as setting these fuses incorrectly will cause the unit to not operate correctly. 9.1 JTAG fuse This fuse enables users to use the Atmel JTAG pod for in-circuit code debugging.
