Description :

The GY-9255 sensor uses MPU-9255 chip which is a 9-axis sensor which packages the accelerometer, gyroscope, magnetometer together each provides data for x, y and z-axes. Other than the three mentioned sensors, it also has other features like Pedometer, Motion and Tap detection, and Temperature. It’s really sensitive low field magnetic sensor. MPU-9255 is also designed to interface with multiple non-inertial digital sensors, such as pressure sensors, on its auxiliary I2C port and it guaranteeing optimal motion performance for users.

pin :

• The input voltage is about 3.3 volt usually from Arduino kit.
• SCL: Clock line for I2C or SPI communication it may connect to pin 5 of the Arduino or pin 21 of the Mega 2560 in SPI mode this is the clock line.
• SDA: Data line for I2C or SPI. For I2C it connects to Arduino pin 4 or Mega 2560 pin 20. For SPI it is data input line.
• EDA and ECL: These two pins are for serial communication to the external sensor or device. 2
• ADO: In I2C mode, it is used to define the address of the sensor. In SPI mode, this is the data output line.
• INT: Interrupt line where the sensor can notify the Arduino when data is ready or motion is detected, depending on the configuration.
• NCS: Chip select pin, used in SPI mode.
• FSYNC: Can be used for different purposes depending on the configuration.
