Hello Freescale Community, Most of the new Freescale Sensors in our portfolio come in very small packages , s ome of them as small as 2x2x1mm, which is awesome! However, one of the problems that we detected last year is that many customers struggle in the evaluation stage of the project due to the small packages. They should either, buy an evaluation board or spend valuable time designing and manufacturing a PCB just for testing our devices. Our goal with this project is to share with our community the Freescale Sensors Breakout Boards we designed for this specific purpose, so you can easily manufacture your own sensor boards or modify our designs to fit your specific application. This way you can easily evaluate Freescale sensors. The boards were designed to be used in a prototype board (DIP style pins) and they can communicate to any MCU thru IIC or SPI (depending on the sensor). These designs were made using Eagle Layout 6.5, if you want to modify the designs you can do it with the free version of Eagle CAD (for non-commercial purposes), or you can send the gerber files (included in the zip files) to your preferred PCB manufacturer. The following designs are available: + Altimeter: MPL3115A2 Breakout Board + Accelerometer: MMA845x Breakout Board MMA865x Breakout Board MMA8491 Breakout Board FXLN83xx Breakout Board FXLS8471 Breakout Board MMA690x Breakout Board + Accelerometer + Magnetometer (6-DOF): FXOS8700 Breakout Board + Gyroscope: FXAS2100x Breakout Board The above .ZIP files, contains the following design information: - Schematic Source File (.SCH) - Schematic (.PDF) - Layout Source File (.BRD) - Layout Images (.jpg) - Gerber Files (GTL, GBL, GTS, GBS, GTO, GBO, GKO, XLN). - PCB Render Image (.png created in OSH park) - BOM (.xls) Additional content: If you want to modify our designs, please download the attached library file "Freescale_Sensors_v2.lbr" and add it to your Eagle Library repository. We'll be more than glad to respond to your questions and please, let us know what you think. -Freescale Sensor's Support team.
This is the 9 December 2014 build of Vibration Monitoring program written by Mark Pedley in the Sensors Solutions Division systems/algorithms team. It is compatible with Freescale FRDM-KL25Z/KL26Z/KL46Z/K64F Freedom development platforms. You can flash your board using the File->Flash pull-down menu. The application contains an option for controlling motor bias and feedback via optional motor control shield to be discussed in an upcoming Freescale blog. Use the View->Motor Controls pull-down to enable those functions.
The following video shows how to run the FRDM 6DOF Bare Board eCompass using the FRDM-K22. This algorithm uses the FXOS8700 contained on the Freedom Board. In order to get more information about the Sensor Fusion Library for Kinetis MCU's 5.0, please refer to the following link: Sensor Fusion|Freescale I hope this material will be useful for you. David
Freescale’s FXOS8700CQ 6-axis sensor combines industry leading accelerometer and magnetometer sensors in a small 3 x 3 x 1.2 mm QFN plastic package. The 14-bit accelerometer and 16-bit magnetometer are combined with a high-performance ASIC to enable an eCompass solution capable of a typical orientation resolution of 0.1 degrees and sub 5 degree compass heading accuracy for most applications. Applications include eCompass, enhanced user interface, augmented reality, and location based services (static geographic heading). Target products include smartphones, tablets, personal navigation devices, remote controls for smart TV’s, watches, gaming controllers, robotics, and unmanned air vehicles (UAVs). Here is a Render of the FXOS8700 Breakout- Board downloaded from OSH Park: And here is an image of the Layout Design for this board: In the Attachments section, you can find the Schematic Source File (.SCH), Schematic PDF File, Layout Source File (BRD), Gerber Files (GTL, GBL, GTS, GBS, GTO, GBO, GKO, XLN) and BOM for this Breakout-board.

The MMA845xQ is a smart low-power, three-axis capacitive micromachined accelerometer up to 14 bits of resolution. This accelerometer is packed with embedded functions with flexible user-programmable options, configurable to two interrupt pins. Embedded interrupt functions allow for overall power savings relieving the host processor from continuously polling data. There is access to both low-pass filtered data as well as high-pass filtered data, which minimizes the data analysis required for jolt detection and faster transitions. The device can be configured to generate inertial wake-up interrupt signals from any combination of the configurable embedded functions allowing the MMA845xQ to monitor events and remain in a low-power mode during periods of inactivity.
