GY-85 Features:
Model : GY-85 — Multiple sensors in a chip or on a board.
9DOF : Sensor Module — Nine degrees of Freedom — 9 axis modules
Ultralow power : as low as 23 μA in measurement mode
Fixed 10-bit resolution Full resolution, up to 13-bit resolution at ±16 g
Free-fall detection
Supply voltage range : 2.0 V to 3.6 V
I2C digital interfaces : this board connect CS to 3.3V to tell the sensor we will be using it as an I2C device, and not an SPI device
3 Chips on board : They are (With their respective 7-bit addresses):
ADXL345 – 0x53 — Three axis acceleration
ITG3205 – 0x69 — Three axis gyroscope
HMC5883L – 0x1E — Three axis magnetic field
ps: for accel chip the alternate IIC address of 0x53 can be chosen by grounding the SDO/ALT ADDRESS pin (Pin 12). That’s exactly what this board does!
