Measures accelerations on three axes simultaneously. By measuring the acceleration of the robot, one can calculate the velocity of the robot or the distance this robot has traveled. Accelerometers are also great for detecting collisions and determining if the robot is stopped or moving. Three Axis Accelerometer Selectable sensitivity via jumper: ±2g and ±6g 0-5V analog output (one for each axis) Uses the LIS344ALH chip LED indicates power and proper connection Mounts directly to robot
