Introduction
Overview:
The GY-85 is a compact 9-axis inertial measurement unit (IMU) which is the combination of three on board sensors.
1. Gyroscope — ITG3205
It measures angular velocity (rotation speed)
Axes: X, Y, Z
Result : °/second
2. Accelerometer — ADXL345
It measures tilt and acceleration.
Axes: X,Y,Z
Able to identify:
movement due to gravity (tilt)
Beneficial for: motion detection and balance
3. Magnetometer — (HMC5883L / IST8310 variant) It determines the magnetic field of Earth
provides a heading for the compass (North)
Interference-sensitive
Chips:
ITG3205 (3-axis gyroscope) ADXL345 (3-axis accelerometer) HMC5883L (3-axis digital compass) - IST8310 from 01.03.2020
Technical data:
IIC communication protocol Built-in regulator and logic converter to support 3.3V/5.0V microcontrollers I2C Digital Interface Module size: 22mm * 16.8mm Mounting hole 3mm 2.54 mm standard pin interface, convenient bread plate experiment connection Scope of delivery:
1x GY-85 (ITG3205 ADXL345 HMC5883L/IST8310) Nine Axis Modules 2x Pin Header
