MaxStream Xbee Series 2

• 2.4 GHZ• Up to 250Kbps• UART Interface• 2mW Transmit Power

Yitran IT800D-SPIM

• DCSK (Differential Code Shift Keying)

• Hardware Forward Error Correction

• Collision Avoidance• Up to 7.25Kbps• UART Interface• Arrived Yesterday

Prototyping

• Plan to make simple breakout board with MAX233 and line coupling components to interface PC directly with XBee module and SPIM.

• Test basic functionality and config

• Aide software development

Power System – Specifications

• Wide load variation regulated supply– 3.3V Load Variation 52 A to 402 mA– 12 V Load Variation 50 mA to 260 mA

• Uninterrupted operation (All modules) – High efficiency 3200mAh Li-Ion battery– Integrated inline charger

• Worst case efficiency is 50%

Sensor - Types

• Motion Sensor– Powered from single 3.3 V supply.– Produces an interrupt.

• Cell Phone Detector– Powered from single 3.3 V Supply.– Produces a V/dB output of the power level

• Temperature Sensor– Located on sensor I/F board– Data taken transferred serially over SPI interface.

Sensor – Interface Features

• Generic sensor interface for most sensors

• DIP switch to identify sensor type and ID

• Generates interrupt based on analog level

• Noise immunity provided by coax transmission lines
