6DOF IMU 26 Click

How does it work?

6DOF IMU 26 Click is based on the SCH16T-K01, a high-performance six-degrees-of-freedom (6DOF) motion sensor from muRata. This device combines a 3-axis gyroscope and a 3-axis accelerometer into a single package, communicating via a digital SPI interface for efficient data transfer. Designed to deliver precision and stability even under demanding conditions, the SCH16T-K01 supports a wide range of configurable options that enhance its adaptability across various applications. The gyroscope offers an in-application selectable measurement range from 300 degrees per second down to 62.5 degrees per second, while the accelerometer supports a selectable range from ±80 m/s² down to ±15 m/s², with a typical default dynamic range of up to ±260 m/s². The sensor also integrates output interpolation and decimation options, allowing flexible data handling and processing tailored to specific needs.

The SCH16T-K01 also features adjustable low-pass filters for both angular rate and acceleration, with cut-off frequencies ranging from 13Hz to 370Hz, ensuring clean signal acquisition even in noisy environments. Built to meet the rigorous AEC-Q100 automotive qualification standard, the SCH16T-K01 is ideal for use in inertial measurement units (IMUs), inertial navigation and positioning systems, dynamic inclination detection, machine control and guidance, robotic platforms, and unmanned aerial vehicles (UAVs), making 6DOF IMU 26 Click a versatile solution for motion tracking in harsh or mission-critical environments.

This Click board™ is designed in a unique format supporting the newly introduced MIKROE feature called "Click Snap." Unlike the standardized version of Click boards, this feature allows the main sensor area to become movable by breaking the PCB, opening up many new possibilities for implementation. Thanks to the Snap feature, the SCH16T-K01 can operate autonomously by accessing its signals directly on the pins marked 1-8. Additionally, the Snap part includes a specified and fixed screw hole position, enabling users to secure the Snap board in their desired location.

This Click board™ establishes communication with the host MCU using a 4-wire SPI interface with maximum clock frequency of 10MHz, ensuring reliable and high-speed data transfer. The SPI address of the SCH16T-K01 can be easily configured via onboard jumpers marked ADDR SEL in the Snap area, allowing multiple devices to coexist on the same bus. In addition to the interface pins, the 6DOF IMU 26 Click also uses the RST pin for resetting the SCH16T-K01, and DRY pin as data ready signal that ) outputs an interrupt signal for host MCU when the internal output registers (gyroscope + accelerometer) have been updated.

This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. It also comes equipped with a library containing functions and example code that can be used as a reference for further development.

Click Snap

Click Snap is an innovative feature of our standardized Click add-on boards, designed to bring greater flexibility and optimize your prototypes. By simply snapping the PCB along predefined lines, you can easily detach the main sensor/IC/module area, reducing the overall size, weight, and power consumption - ideal for the final phase of prototyping.
