4. How to use
We will illustrate the usage of the module with an example of working with a STM32 series’
development board.
① Download the relative codes to the development board.
② Connect the development board to a PC via a serial wire, and insert the module into
the I2C 2 interface on the development board. Please take attention to the
connection between the module and I2C 2 interface, each pin of the module should
be connected to its corresponding port on the I2C 2 interface and FSYN pin should
be kept suspended respectively.

④ After powering 10 DOF IMU Sensor on, firstly, acceleration is calibrated at horizontal
state, and magnetic is calibrated later. After done, the qualify data will output from
