Ok, I ordered the 6DOF IMU. It has I2C interface, not SPI. Standard speed is 100k/s, faster speed is 400k/s. To poll the sensor we need the Wire library, I have experience working with I2C sensors and I have 4 Arduinos on a robot linked through I2C interface. So, I hope it will work fine. The only thing I have a problem with is the 3.3V interface. I'll see what I can do. I think I need to use 4.7k pull up resistors tied to 3.3V instead of 5V. Also, the sensor needs 3.3V that I will get from the Arduino board directly (I still need to check the current requirements).
I will create a blog page with my attempt, although it did not work because of the design I tried just to see if it works. New version coming as soon as I will get the new IMU.
