6DOF IMU 18 Click Board™

Product Code: MIKROE-5591

How Does The 6DOF IMU 18 Click Board™ Work? The 6DOF IMU 18 Click Board™ is based on the ICM-42605, a 6-axis motion tracking device that combines a 3-axis gyroscope and a 3-axis accelerometer from TDK InvenSense. It features a 2K-byte FIFO that can lower the traffic on the selected 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. With its 6-axis integration, the ICM-42605 guarantees optimal motion performance for customers. The IICM-42605 supports an extended operating temperature range, allowing customers to design it into various industrial IoT applications, including navigation and stabilizing industrial machinery and robots. The gyroscope supports eight programmable full-scale range settings from ±15.625dps to ±2000dps, and the accelerometer supports four programmable full-scale range settings from ±2g to ±16g. Other industry-leading features include on-chip 16-bit ADCs, programmable digital filters, an embedded temperature sensor, and programmable interrupts.

The ICM-42605 also provides high robustness by supporting 20,000g shock reliability. This Click board™ allows using both I2C and SPI interfaces at a maximum frequency of 1MHz for I2C and 24MHz for SPI communication. Selection is made by positioning SMD jumpers marked COMM SEL to the appropriate position. All jumpers must be on the same side, or the Click board™ may become unresponsive. When the I2C interface is selected, the ICM-42605 allows the choice of its I2C slave address, using the ADDR SEL SMD jumper set to an appropriate position marked 1 or 0. In addition to communication pins, this board also possesses additional interrupt pins, routed to the INT and IT2 pins on the mikroBUS™ socket, to signal MCU that an event, such as specific tap or sample acquisition conditions, has happened. Besides the standard interrupt function, the IT2 pin can also be used as a Frame Synchronization signal for synchronization with an external digital signal. Thie 6DOF IMU 18 Click Board™ can only be operated with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. However, the Click board™ comes equipped with a library containing functions and an example code that can be used as a reference for further development.
