BMP085 9-Axis IMU Magnetic Acceleration Gyroscope Atmospheric Pressure Module

The BMP085 9-Axis IMU Magnetic Acceleration Gyroscope Atmospheric Pressure Module is a 9-axis module in one board, with a combination of L3G4200D + ADXL345 + HMC5883L +BMP085.  L3G4200D 3x axis gyrometer sensor and ADXL345 in  3 axes Accelerometer sensor, HMC5883L triple-axis magnetometer, BMP085 barometric pressure sensor. This module consists of an ultra-low noise LDO voltage regulator and onboard filters, thus reducing noise from the motor and high current.

L3G4200D designed as a 3-axis angular rate sensor (yaw, pitch & roll) makes it great for model aircraft navigation systems. Raw angular rate and temperature data measurements accessed from the selectable digital I2C or SPI interface. ADXL345 is an integrated, compact, ultra; low power, 3-axis MEMS accelerometer with signal conditioned voltage output. Moreover, this is the breakout board for analogue devices used for sensing motion and accelerometers using I2c or SPI communication. It offers sense in the range of ± 2 ± 4 ± 8 ± 16 g.

The HMC5883l is designed as a surface mount multi-chip module designed for low field magnetic sensing with a digital interface for applications such as low-cost compassing and magnetometer. These 12 bit ADC enables 1 degree to 2 degrees heading accuracy. These modules are commonly used in mobile phones, notebooks, consumer electronics, auto navigation systems, and personal navigation devices. BMP085 is defined as a highly précised sensor used to measure barometric pressure and temperature. Although this board is 5V Compliant, comes with a 3.3V regulator. And an I2C level shifter circuit and hence can use this sensor safely with 5v logic.
