TDK Launches 6-axis IMU With High Motion Sensor Performance for IoT, Robotics, AR/VR and Wearable Applications
TDK Corp. has made available the InvenSense ICM-42688-P high-performance motion sensor, a 6-axis MEMS MotionTracking device that combines a 3-axis gyroscope and a 3-axis accelerometer in a 2.5mm x 3mm x 0.9mm package.
The device enables high-precision motion sensing applications such as robotics, wearable devices, drones and many other IoT devices.
Compared to traditional consumer-grade IMUs, the ICM-42688-P provides a 40% lower noise-figure and improves temperature stability by 2x, ensuring any motion event is measured with the highest accuracy, independent of temperature changes. TDK says that the ICM-42688-P also includes two key features not available in any other consumer-grade IMU: a 100% accurate clock that eliminates timing errors and a high-resolution analog-to-digital converter. The converter enables an 8x increase in gyroscope resolution and a 4x increase in accelerometer resolution. Other features include the InvenSense on-chip APEX Motion Processing Engine for gesture recognition, activity classification, and pedometer, along with programmable digital filters, and an embedded temperature sensor.
A development platform, the DK-42688-P, along with necessary software is available to enable quick-to-market development of customer systems.
The DK-42688-P features:
- Single Board “Out of the Box” experience
- Comprehensive software tools to expedite evaluation and development
- MotionLink and embedded motion driver (eMD)
- On-board embedded developer tools to help with code development
- 15-minute setup time
- Highest-precision Gyro/Accel
- Further improved Gyro/Accel performance
- 18-bits (Accel),19-bits (Gyro) output option
- I3CSM Support
- APEX Motion Engine
- RTC Input
- 5mm x 3mm x 0.9mm package
The InvenSense ICM-42688-P and DK-42688-P developer kit are available from multiple distributors.
