Featuring the MXC4005XC, a 12-bit three-axis thermal accelerometer from MEMSIC, this board offers selectable full-scale acceleration measurements of ±2g, ±4g, or ±8g in three axes with a compatible I2C serial interface with 400KHz fast mode operation.
High Accuracy and Advanced Functionality
In addition to its high accuracy, low offset, and temperature signal, the MXC6655XA also detects six orientation positions, X/Y shake, and shake directions with an appropriate interrupt signal for these states. This Click board™ is perfect for various information appliances, consumer electronics, household safety applications, and more.

How Does The Accel 25 Click Board™ Work?
The Accel 25 Click Board™ is based on the MXC4005XC, a highly reliable digital triaxial acceleration from MEMSIC. The MXC4005XC is highly configurable with a programmable acceleration range of ±2g, ±4g, or ±8g based on MEMSIC's proprietary thermal technology built with a 0.18μm standard CMOS process. It contains no moving sensor parts, eliminating field reliability and repeatability issues; there is no measurable resonance (immunity to vibration), no stiction, and no detectable hysteresis.
The MXC4005XC also eliminates the "click" sounds typically heard in ball-based orientation sensors. The shock survival of this MEMS sensing structure is greater than 200,000g. This sensor provides X/Y/Z axis acceleration signals with a low 0g offset and temperature signals with high accuracy. In addition, it also detects six orientation positions, X/Y shake, and shakes directions.
The Accel 25 Click Board™ communicates with MCU using the standard I2C 2-Wire interface to read data and configure settings capable of operating in a standard or fast mode of operation. The acceleration signal is provided in 12-bit output resolution. In addition to communication pins, this board also possesses an additional interrupt pin, routed to the INT pin on the mikroBUS™ socket, for orientation and X/Y shake detections. The MXC4005XC allows users to be placed in a Power-Down mode enabled through the I2C interface.
This 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.
