The DFRobot 10 DOF sensor module contains 4 different I²C sensors:
- Adxl345 accelerometer
- ITG3200 gyro
- HMC5883L Compass
- 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:
