특징

This IMU sensor has 6 degrees of freedom - 3 degrees each of linear acceleration and angular velocity at varying rates within a respectable range. For the accelerometer: ±2/±4/±8/±16 g at 1.6 Hz to 6.7KHz update rate. For the gyroscope: ±125/±250/±500/±1000/±2000/±4000 dps at 12.5 Hz to 6.7 KHz. In particular, this is one of the few gyro's we stock with 4000 dps range, usually they top out at 2000. This sensor has extra calibration and compensation circuits to give it excellent performance in a wide environmental range from -40 to +105°C. Most other IMU sensors don't have industrial temperature ranges, or have wide accuracy variation as the temperature changes. The accelerometer and gyroscope also are on the same silicon die, which will keep the 6 measurements synchronized better than when the two sensors are on separate dies.
There are also some nice extras, such as built in tap detection, activity detection, pedometer/step counter and a programmable finite state machine / machine learning core that can perform some basic gesture recognition.
For interfacing, you can use either SPI or I2C - there's two configurable interrupt pins. For advanced usage, you can attach additional devices to an external I2C/SPI port - used for optical image stabilization.
To make getting started fast and easy, we placed the sensors on compact breakout boards with voltage regulation and level-shifted inputs. That way you can use them with 3V or 5V power/logic devices without worry.
