What project could possibly require 14 IMUs, and even if so, why does it have to go through one Arduino? You can buy a Pro Mini on eBay for $2!
I'm making a motion tracker as input for a robotic hand. I figured it'd be easier to route all the data through one device, instead of say, 7 Pro Minis.

If you use a 3.3volt Arduino, then you still have the problem of the I2C pull up resistors.
You can only leave two 2k2 sets.
Leo..
I still don't understand what you mean by the I2C pull up resistors. Using 3.3V Arduino, you can set the AD0 on the sensors, no?
