placement of Inertial mesurement ICs on pcb
« on: December 08, 2013, 05:45:07 PM »
i have a very basic doubt regarding the device placement of gyro, accelerometer and magnetometer on various IMU sensors available e.g. http://www.pololu.com/product/1269.

Are they not required to be place on the exact center of PCB to get best performance (i understand it require to be stack design). Are we not compromising performance of these devices by placing it offset to center? And is there particular measurement to place gyro and accelerometer and magnetometer apart?

No, they do not need to be in the center of the PCB or even in the center of what ever project the PCB is mounted in.
Even inside one IC each of the three axes are not in the center of the chip.

For any application that may require the IMU frame to be in the center there are ways to calibrate the sensors to compensate for being off-center.
