GY80 is 5v and 3.3v compatible. Use one of the following depending on your interface voltage: VCC - For +5v power. If using with boards such as an Arduino UNO, Leonardo, Micro, Mega. VCC_3.3v - For +3.3v power. If using with boards such as an Arduino Due. SCL - I2C Clock SDA - I2C Data The quickest way to verify your board is connected properly is running the following I2C scanner program. This simple sketch will print the I2C address of all discovered devices to the serial monitor. GY-80 has the following sensors on board: Barometer and thermometer - Measures atmospheric pressure and temperature. Used for weather applications 3 Axis Accelerometer - Measures acceleration. Can be used to sense linear motion, vibration, and infer orientation and force. 3 Axis Gyroscope - Measures angular rotation which can be used to infer orientation. 3 Axis Magnetometer - Measures strength and direction of magnetic fields. Can be used as a compass to determine bearing. I2C Device Addresses I2C Address 0x1E is the HMC5883L I2C Address 0x53 is the ADXL345 I2C Address 0x69 is the L3G4200D I2C Address 0x77 is the BMP085
