IMU

1

• 6-23-09 : seems to be working
• 1-24-09 : boots and can reprogram - this will be the IMU development device.

• 1-24-09 : removed broken jumper wires from GND to R28. Shorted Q4 gate to ground.
• 1-24-09 : is missing pushbutton switch and is missing PB pad. Remain 3 pads don't seem to be enough to switch the system on.

2

• 6-23-09 : seems to be working with 'blue' cable w/red and black marks on connector
• 1-24-09 : was able to erase and reprogram.
