Re: Gyro Smoking
 

Diagnosis continues.

I wired the GYRO up to a 5V supply with no heating apparent.

Made me suspect the CRio.

I measured the voltage on the red/black pins on the analog breakout and got 12V. Hmm not good.

The LED is green, and the input voltage is 12V, but I guess the DC-DC converter on the breakout is bad.... Not sure if it's a new one or not.

Might explain why my 2090 Gyro was drifting badly on this year's robot.

Off to the parts bin.

Update. ----------------------

Found a spare Analog Breakout....

This one puts out 5V like it should. No hot Gyro any more.....

Note: the black chip on the bad breakout was also getting hot...(U1)

Now... wonder if it still works.

Re: Gyro Smoking
 

Is this a 2010 or a 2009 Analog breakout?

Re: Gyro Smoking
 

That's what I meant by "new or not", I wasn't there when they assembled the prototype, so I'm not sure. Can you tell them apart?

If there was only one analog module in the 2010 KOP, then the one that went bad must have been a 2009.

Eric made the 2010 Analog Breakout blue, while the 2009 one was red.
