Guys, I have a question, since I won $40 loyalty from SF, I want to get a new IMU board. Question is: should I get the recommended 5DOF IMU ($44.95) OR should I get the new 6DOF IMU that uses I2C ($64.95)?
The advantage of the last one being freeing the analog pins so I can use pots to fine tune the PID and perhaps a better accuracy. But is I2C fast enough in this case? Also the acc-meter has 2 interrupt output pins that you can program to trigger when falling too fast or when new measurement is ready, etc.
