Introduce precision and efficiency to your gesture-based handheld applications with the Air Motion Click Board™. This compact add-on board contains a 6-axis inertial measurement unit featuring the ICM-40627 from TDK InvenSense - a 6-axis MEMS MotionTracking™ device that combines a 3-axis user-selectable gyroscope and accelerometer.
Experience the convenience of the ICM-40627's bundle with TDK's Air Motion Library, enabling precise mouse pointing, swipe, roll and other motion gestures, communicating with the host MCU via a configurable interface (I2C and SPI serial communication). The ICM-40627 also features a 2KB FIFO and two programmable interrupts with ultra-low-power Wake-on-Motion support to minimize system power consumption, making it a perfect fit for pedometer, tilt and tap detection and more.
Easily integrate the Air Motion Click Board™ into your system with the mikroSDK-compliant library, which includes functions that simplify software development. And with the added bonus of being a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket, you can trust that the Air Motion Click Board™ will deliver the precise motion tracking results you need. Upgrade your technology today and experience the difference with the Air Motion Click Board™.
How Does The Air Motion Click Board™ Work?
The Air Motion Click Board™ is based on the ICM-40627, a 6-axis MotionTracking™ 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-40627 guarantees optimal motion performance for customers. The ICM-40627 comes bundled with TDK's Air Motion Library that enables precise mouse pointing, swipe, roll, gesture wake-up and other motion gestures, making this Click board™ a suitable solution for gesture-based handheld applications.
The gyroscope supports eight programmable full-scale range settings from ±15.65dps to ±2000dps, and the accelerometer supports four programmable full-scale range settings from ±2g to ±16g. Other industry-leading features include InvenSense on-chip APEX Motion Processing engine for gesture recognition, activity classification, and pedometer, along with on-chip 16-bit ADCs, programmable digital filters, an embedded temperature sensor, and programmable interrupts.
The Air Motion Click Board™ allows 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 marked 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. While the I2C interface is selected, the ICM-40627 allows choosing the least significant bit (LSB) of its I2C slave address using the ADDR SEL SMD jumper to an appropriate position marked as 0 and 1.
The ICM-40627 also has a programmable interrupt system, configured via the Interrupt Configuration register, that can generate an interrupt signal on the INT pins, INT1 and INT2 pins routed on the INT and AN pins of the mikroBUS™ socket. Events like new read-data availability (from the FIFO and Data registers), accelerometer events, FIFO watermark and overflow can all trigger an interrupt.
The Air Motion 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. 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.
