1. Current Works Soldered pins onto IMU, XBee breakout board, and 3.3V regulator Successfully powered XBee off of 2 AA batteries using the voltage regulator Configured and tested serial communication between 2 XBees

2. Current Test Setup

3. XBee A/D Conversion problems Only 4 pins for input- going to need more because IMU has 5 outputs – Could be solved by using a MUX Can only read voltages between 0 volts and 1.2 volts- voltages can be scaled down using resistors but will lose some precision – Future testing needed with IMU to determine how significant this problem is XBee freezes up whenever the required A/D firmware is downloaded Possible solution- use Microprocessor to perform A/D conversion and send to XBee using serial communication – Microchip offers free samples of their microprocessors and there are small chips specializing in A/D conversions

4. What’s Next? Begin testing accelerometer and gyroscope output on IMU with the assistance of MobileStudio Board – Determine output range If Xbee conversion will be precise relative to results form IMU testing, continue researching and programming Xbee to perform A/D conversions Research other A/D conversion chips/microprocessors
