6DOF IMU 6 Click features a 6-axis MotionTracking device that combines a 3-axis gyroscope, a 3-axis accelerometer, and a Digital Motion Processor™ (DMP) labeled as ICM-20689. The ICM-20689 from company TDK InvenSense includes on-chip 16-bit ADCs, programmable digital filters, an embedded temperature sensor, and programmable interrupts. The gyroscope and accelerometer are full-scale range, user-programmable sensors with factory-calibrated initial sensitivity for reduced production-line calibration requirements.
6DOF IMU 6 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.
The 6DOF IMU 6 Click uses ICM-20689, a 6-axis MotionTracking device that combines a 3-axis gyroscope, a 3-axis accelerometer, and a Digital Motion Processor™ (DMP) in a small 4x4x0.9mm (24-pin QFN) package. It also features a 4 Kbyte FIFO that can lower the traffic on the serial bus interface, and reduce power consumption by allowing the system processor to burst read sensor data and then go into a low-power mode.The ICM-20689, with its 6-axis integration, on-chip DMP, and run-time calibration firmware, enables manufacturers to eliminate the costly and complex selection, qualification, and system level integration of discrete devices, guaranteeing optimal motion performance.
The gyroscope has a programmable full-scale of ±250, ±500, ±1000, and ±2000 degrees/sec. The accelerometer has a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g. Factory-calibrated initial sensitivity of both sensors reduces production-line calibration requirements. Other industry-leading features include on-chip 16-bit ADCs, programmable digital filters, an embedded temperature sensor, and programmable interrupts. The device provides high robustness by supporting 10,000g shock reliability.
The device features I2C and SPI serial interfaces, wide operating voltage range (VDD) and separate digital IO supply (VDDIO) from 1.71V to 3.45V. Communication with all registers of the device can be performed using either I2C at 400kHz or SPI at 8MHz.
6DOF IMU 6 Click supports both SPI and I2C communication interfaces, allowing it to be used with a wide range of different MCUs. The communication interface can be selected by moving SMD jumpers grouped under the COM SEL to an appropriate position (SPI or I2C). The peripheral I2C address can also be configured by an SMD jumper when the Click board™ is operated in the I2C mode. An SMD jumper labeled as ADD SEL is used to set the least significant bit (LSB) of the I2C address.
Excellent choices for applications include mobile phones, tablets, drones, handset and portable gaming, motion-based game controllers, wearable sensors for health, fitness and sports and 3D remote controls for internet-connected DTVs and set-top boxes and 3D mice.
