• Firmware was successfully uploaded on April 15th by Andrew
• Tested board again to make sure the voltages are consistent
• One of the inductors between 3.3V regulator and 5V booster becomes really hot only when Xbee is plugged in
• We resolved the issue of the heating inductor by replacing it with another one that is rated at a higher current rating.
• The Xbee is now receiving ~3.9V instead of less than 3.3V
• We tried to put a diode between the 3.3V regulator and the Xbee power supply pin to lower the ~3.9V to ~3.3V with a voltage drop of approximately ~0.5V from the diode.
• The Xbee is still receiving ~3.9V even after that; so, we decided to replace the 3.3V regulator to see if the problem was from the 3.3V regulator.
• The problem still exists so we desoldered the whole 3.3V regulator and tested the voltage at the Xbee power supply pin
• 3.9 V still measured at the XBee power pin even when the 3.3V reg is taken off

• Final Presentation soon^(TM)
• Poster Presentation soon^(TM)
