The IMU Brick 2.0 is the successor of the IMU Brick with higher resolution sensors, easier recalibration, additional continuous self-calibration and an accuracy increase by two orders of magnitude.
The IMU Brick 2.0 is equipped with a 3-axis accelerometer, magnetometer (compass) and gyroscope and works as a USB inertial measurement unit. It can measure 9 degrees of freedom and computes quaternions, linear acceleration, gravity vector as well as independant heading, roll and pitch angles. It is a complete attitude and heading reference system.
The API, provided for many programming languages, allows access to the calculated data and also the acceleration, magnetic field and angular velocity of the three axes. If the quaternion representation is used, the IMU Brick 2.0 does not have a gimbal lock, as known from Euler angles.
Two Bricklet ports can be used to extend the features of this Brick. For Example a GPS Bricklet 2.0 can be attached to get position information.
The IMU Brick 2.0 can be use together with other Bricks in a stack. For example an additional Master Brick with Master Extension allows to replace the USB connection by other cable based (RS485, Ethernet) or wireless (WIFI) connections.
A comparison video between IMU Brick 1.0 and IMU Brick 2.0 is available on Youtube:
The IMU Brick 2.0 currently still uses 10-pole Bricklet connectors. You need 10p-7p Bricklet cables to connect Bricklets to it.
