Difference Between Pololu minImu v9 Sensor and MPU9150 Imu Sensor

Hi all!

I'm planning to use Imu sensor for wheelchair but i can't sure which sensor is true on this point. They are almost identical but their price is different. Is there something I missed?

Pololu Imu: https://www.pololu.com/product/1268 Sparkfun: https://www.sparkfun.com/products/11486

Is there something I missed?

The two sensors measure the same physical quantities, but are otherwise completely different.

Do not cross post.

The Pololu board will work with a 5V Arduino; the Sparkfun board requires 3.3V signals or you’d need to add a level shifter. IMHO that’s the important part.

The Sparkfun/MPU-9150 is a more advanced chip but those features probably aren’t going to be important to your project.
