What are the min and max sample rates for the gyroscope and accelerometer?

The gyroscope and accelerometer can be sampled between 1-8kHz, but the limitations of the SD module will restrict the sample rate down to 500 Hz - which suffices for many applications (full datasheet for MPU6050 here).

What is the minimum allowable sampling frequency?

The sampling theorem states that a real signal, f(t), which is band-limited to f Hz can be reconstructed without error from samples taken uniformly at a rate R > 2f samples per second. This minimum sampling frequency, fs = 2f Hz, is called the Nyquist rate or the Nyquist frequency (6).

What is sampling frequency in accelerometer?

Accelerometer characteristics: sampling frequency: 1–1344 Hz, maximum magnitude: ±24 g).

Is IMU same as accelerometer?

An IMU is a specific type of sensor that measures angular rate, force and sometimes magnetic field. IMUs are composed of a 3-axis accelerometer and a 3-axis gyroscope, which would be considered a 6 axis IMU. They can also include an additional 3-axis magnetometer, which would be considered a 9 axis IMU.
