When I had the robot accelerate hard, it would measure that it had turned. On the adxrs453, I've had no issues with that. 254, 1678, 971, 973 and 1323 all ran a previous version of the board last year and will be running it again this year.

You're right, the ADXRS450/453 is a nice gyro core on its own! If you're looking for high VRE (Vibration Rectification Error) take a look at the ADIS16448. It has much better VRE and lower drift vs the 450.
