Dead IDG 500 and rework IMU

Posted by Gerard Valade on April 9, 2011 at 12:04am

Hello,

I have tested the IMU only two weeks all the components works fine, and after I dont know why,

only IDG 500 doesnt response as you can see on arducopter configurator (blue and red graph).
So I decide to remove the IDG 500 with my hot air soldering and put a breakout card
and now all works fine.

Effectively this will be a great idea because Diydrone's store has a low cost shipping for this kind of product. But how many people can solder this tiny component. I took 3 times before succeeding with my big fingers.

I think you can get it for 4$ at invensense.com plus 21$ or 47$ intl shipping (gloups!).

Mine, I got it from wide.hk, I ask them directly if they sell it and they reply quickly the price and the shipping fee (good price for only one piece).
