This inertial-measurement-unit combines 3 of the best quality sensors available on the market to give you 11 axes of data: 3 axes of accelerometer data, 3 axes gyroscopic, 3 axes magnetic (compass), barometric pressure/altitude and temperature. We tested many different 'combination' sensors and found these were the best value, with stable and reliable readings.The L3DG20H gyroscope + LSM303DLHC accelerometer compass + BMP180 barometric/temperature sensors are all on one breakout here, to save you space and money. Since all of them use I2C, you can communicate with all...
