Hi,
Thanks for your inquiry.
BMI088 is the IMU for drone and robot applications because of its high performance of accel robutness againist vibration and close-loop gyro bias stability. BMI088 gyro has +/-1dps offset and less than 1.7 degree/hour long term bias stability. BMI088 gyro is immune to high switching ICs as long as the frequency range is not in the range of 25KHz +/-4KHz which is from [21KHz to 29KHz].
You said that BMI088 gyro works fine on a breakout PCB. Please check your own PCB design such as power supply ripple and digital interface circuit, etc.
Thanks.
