MEMS Sensors Evaluation Kit with NXP FRDM-KL25Z Freedom Platform

The low-cost sensors evaluation kit, XTRINSIC-SENSORS-EVK, includes a multi-MEMS sensor board based on three Xtrinsic sensors and the NXP FRDM-KL25Z Freedom platform. It contains the software code for design engineers to easily evaluate and demonstrate the performance of the sensors in a variety of applications including eCompass, Mobile Phones/Tablet Computers, Remote Control/Wireless Mouse, Game Consoles, Navigation Devices, Medical Devices, etc.

The Xtrinsic MEMS sensors board features three types of Xtrinsic sensors from NXP, including MPL3115A2, MAG3110 and MMA8491Q. Included in the kit are the software drivers and code that enables users to easily evaluate and demonstrate the performance of the sensors to measure altitude, pressure, as well as detection of magnetic fields and physical position.

MPL3115A2 Absolute Xtrinsic Smart Pressure Sensor

The MPL3115A2 provides highly precise pressure and altitude data with variable sampling rate capability. It has very low-power consumption, smart features and requires zero data processing for mobile devices, medical and security applications. The Xtrinsic MPL3115A2 pressure sensor smart features include digital output, two interrupts for auto-wake, minimum/maximum threshold detection and autonomous data acquisition. MCU usage can be limited since the MPL3115A2 pressure sensor can process sensor data locally, reducing communications required with the host processor.

MAG3110 Xtrinsic High Accuracy, 3D Magnetometer

The MAG3110 is a small, low-power digital 3-D magnetic sensor with a wide dynamic range to allow operation in PCBs with high extraneous magnetic fields. The MAG3110 magnetometer measures the three components of the local magnetic field which will be the sum of the geomagnetic field and the magnetic field created by components on the circuit board. Used in conjunction with a 3-axis accelerometer, orientation-independent accurate compass heading information can be achieved. The MAG3110 features a standard I²C serial interface and is capable of measuring local magnetic fields up to 10 Gauss with output data rates (ODR) up to 80 Hz.

MMA8491Q Xtrinsic 3-Axis, Digital Accelerometer

The Xtrinsic MMA8491Q 3-axis accelerometer is an ultra-low-power tilt sensor that enables smart meters, home appliances, asset tracking applications, gaming and remote controls through auto-on/auto-sleep energy-efficient operation housed in a specialized industrial package. The Xtrinsic MMA8491Q accelerometer is simple, yet robust with reduced system and implementation cost for reduced development time. Its unique single sample and hold measurement method allows for ease of use.

The MEMS sensors board is connected to FRDM-KL25Z Freedom board via J2 and J9 I/O header on FRDM-KL25Z board. The FRDM-KL25Z features a KL25Z128VLK - a KL2 family device boasting a max operating frequency of 48MHz, 128KB of flash, a full-speed USB controller, and loads of analog and digital peripherals. The Xtrinsic MEMS sensors evaluation kit also provides the software for easily evaluating and interacting with MPL3115A2, MAG3110 and MMA8491Q Xtrinsic sensors.
