6DOF IMU 17 Click Board

How Does The 6DOF IMU 17 Click Board™ Work?

The 6DOF IMU 17 Click Board™ as its foundation uses the IIM-42652, 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 IIM-42652 guarantees optimal motion performance for customers. The IIM-42652 supports an extended operating temperature range up to 105°C, allowing customers to design it into a wide range of 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 IIM-42652 also provides high robustness by supporting 20,000g shock reliability.

The 6DOF IMU 17 Click Board™ provides the possibility of using both I2C and SPI interfaces with a maximum frequency of 1MHz for I2C and 24MHz for SPI communication. The selection can be made by positioning SMD jumpers labelled as COMM SEL to an appropriate position. Note that all the jumpers' positions must be on the same side, or the Click board™ may become unresponsive.

Interrupt functionality is configured via the Interrupt Configuration register, which allows for interrupt pin configuration routed to the INT pin of the mikroBUS™ socket (used to signal MCU that an event has been sensed), the interrupt latching and clearing method, and triggers for the interrupt. The interrupt status can be read from the Interrupt Status register.

The 6DOF IMU 17 Click Board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before use with 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.
