6-Axis MEMS-Based IMU Optimised for Use in Drones & Robots

30 January 2024

TDK InvenSense’s IIM-20670 MotionTracking 6-axis inertial measurement unit (IMU) can now be sourced via Mouser Electronics.

Featuring a 3-axis accelerometer alongside a 3-axis gyroscope, this rugged MEMS-based device delivers high-accuracy measurement capabilities while drawing only 10mA of current. Programmable digital filters, 16-bit data conversion and a built-in temperature sensor (for thermal compensation purposes) are all incorporated. The accelerometer element exhibits a 1.7µg/C thermal stability and a 1mg bias repeatability. System connection is via 10MHz SPI interfacing. Key applications for this device, which is supplied in a space-saving 24-pin DQFN package (with 4.5mm × 4.5mm × 1.1mm dimensions), include robotics, as well as industrial and agricultural drones.
