1.2 Product Description
The RoBoard Module RM-G146 is fully integrated 9-Axis module, combines
3-axis magneto-resistive sensor and 3-axis accelerometer with the LSM303DLH,
and 3-axis angular rate sensor (Gyroscope) with the MPU-3050, simply and all
done through I2C interface, the dimension of it is wee as 20 x 20 mm.
The MPU-3050 is comprised of an embedded 3-axis digital gyroscope. offers a
programmable full-scale range from ±250 to ±2000 degrees per second which
ensures precision tracking of both fast and slow motions.
The LSM303DLH is a system-in-package featuring a 3D digital linear
acceleration sensor and a 3D digital magnetic sensor. It has a linear
acceleration full-scale of ±2 g / ±4 g / ±8 g and a magnetic field full-scale of ±1.3
/ ±1.9 / ±2.5 / ±4.0 / ±4.7 / ±5,6 / ±8.1 gauss, both fully selectable by the user.
