## Description

9DOF module for measuring orientation and motion in robotics and navigation projects, combines on the same PCB ITG3205 gyroscope, ADXL345 accelerometer and HMC5883L magnetometer for 9-axis readings. Communicates via I2C, operates at 3-5V with integrated LLC, is compatible with Arduino and other boards, compact 22 mm format for easy integration.
9-axis module, GY-85, BMP085, compatible with Arduino and other development boards, which displays information 3-axis Gyroscope, 3-axis Accelerometer and 3-axis Magnetometer (compass), its advantage being the fact that it incorporates 3 different integrated on the same PCB, each responsible for reading 3 axes (3 axes * 3 integrated = 9 axes in total).
For the nine axes, it is used by the following integrated:
1. ITG3205
2. ADXL345
3. HMC5883L
Specifications:
Number of axes: 9 (3xGyroscope + 3xAccelerometer + 3xMagnetometer)
Chip: ITG3205 + ADXL345 + HMC5883L
Supply voltage: 3 - 5VDC
Communication protocol: IIC, compatible with 3-5V systems, integrated LLC circuit
Dimensions mm: 22 x
