Individual components

I have the following individual components and am looking for someone who could look over the attached schematic and let me know if I am on the right track. Thank you in advance ~ Rick

Just get a 5V all in one IMU 9DOF or 10DOF with then you can ditch the LLC and have less connections. Plenty to choose from on ebay for a lot less than individual items. Look in the connecting elements on the home page and you will find a diagram on how to connect everything.

Hi Bill516,
We already have one...well..... we have a DIYdrone APM2 which is awesome
But here we want to learn individual components just for fun. And we have looked at the element connecting on the home page and we think this is close ... we just did not find anything with these exact elements and we did not want to fry anything
So do you think this might work?
Thanks,
Rick

You circuit as is should work ok, only thing I'm not sure of is the i2c level shifter but that is only because sparkfun do an llc (bob 08745) and its a lot less money. Another option you could do is use a 3.3v pro mini and do away with the i2c shifter everything would be at 3.3v.
