The XTRINSIC-SENSORS-EVK is an evaluation kit that comes with a sensor board together with the FRDM-KL25Z platform. The software drivers and code enable engineers to easily evaluate and demonstrate the performance of the sensors in a variety of applications. The sensor board comes equipped with three of new generation XTRINSIC MEMS sensors. The MPL3115 is designed for accurate measurement of altitude and pressure, the MAG3110 for detection of magnetic fields, and the MMA8491 for measurement of physical positions. 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 FRDM-KL25Z has an easy access to MCU I/O via Arduino R3 compatible I/O connectors. The freedom board also features a programmable OpenSDA debug interface.
