DFRobot 10 DOF IMU Sensor (SEN0140)

Overview

The SEN0140 is a comprehensive 10 Degrees of Freedom (DOF) inertial measurement unit evaluation board that combines four specialized sensors: the ADXL345 accelerometer, HMC5883L magnetometer, ITG3200 gyroscope, and BMP085 pressure sensor. This compact 18mm x 26mm module provides full motion tracking and altitude sensing via a single I2C interface, supporting a wide input voltage range from 3V to 8V.

Why Choose This Part

This module simplifies hardware design by integrating four high-performance sensors onto a single PCB with shared pull-up resistors and a unified I2C bus. The onboard voltage regulation allows it to operate safely on 3.3V or 5V logic levels, making it directly compatible with most microcontrollers without extra level-shifting circuitry.

Applications

Getting Started

Connect the VCC pin to your controller's power output (3V-8V) and wire the SDA and SCL pins to your microcontroller's I2C bus. Since the board uses well-documented ICs like the ADXL345 and ITG3200, you can use standard open-source libraries available for the Arduino IDE or Raspberry Pi to read data from the individual I2C addresses.
