DFRobot 10 DOF v1.0.jpg

The DFRobot 10 DOF sensor module contains 4 different I²C sensors:

  1. Adxl345 accelerometer
  2. ITG3200 gyro
  3. HMC5883L Compass
  4. BMP085 pressure sensor

Each of these sensors will be handled on a separate page but a general overview follows on this page.

Schematics

DFRobot provides schematics for most of their product. The schematic for the 10 DOF board is this:

As can be seen, all four sensors are wired up to the same I²C bus. It's a pity the individual interrupt lines are not wired out to the header as that would have made the board a LOT more usable.

I²C bus

The four sensors show up on the I²C bus like this:
