This board combines 5 sensors into a single tiny package. Convenient to expirement with different sensors or used together as an inertial management unit. They are all accessible via I2C bus.
Comes with straight and right angle headers.
|Part Number||I2C Address|
|3 Axis Gyro||ST Microelectronics L3G4200D||0x69||Datasheet|
|3 Axis Accelerometer||Analog Devices ADXL345||0x53||Datasheet|
|3 Axis Magnetometer||Honeywell MC5883L||0x1E||Datasheet|
|Barometer + Thermometer||Bosch BMP085||0x77||Datasheet|
All sensors are accessible via I2C bus for basic operation so you will only need 4 wires to get started:
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 and estimating altitude.
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.
Bildr.org has written some great articles on using each of these sensors along with sample code:
