Hello there friend! SparkFun will be closed on 8/17/2018 @2pm for a company event. We will not be offering our normal Friday tour or Local Pickups during this time. We will resume normal operations on Monday 8/20/2018. Any orders placed after 2pm MT on 8/17/2018 will be processed when we resume normal operations. Have a great day!
The SparkFun 9DOF MPU-9150 is the world’s first 9-axis MotionTracking MEMS device designed for the low power, low cost, and high performance requirements of consumer electronics equipment including smartphones, tablets and wearable sensors. And guess what? You get to play with it.
This breakout board makes it easy to prototype with the InvenSense MPU-9150 by breaking out all the pins you need to standard 0.1" spaced headers. The board also provides I2C pullup resistors and a solder jumper to switch the I2C address of the device.
The MPU-9150 is a System in Package (SiP) that combines two chips: the MPU-6050, which contains a 3-axis gyroscope, 3-axis accelerometer, and an onboard Digital Motion Processor™ (DMP™) capable of processing complex MotionFusion algorithms; and the AK8975, a 3-axis digital compass. The part’s integrated 6-axis MotionFusion algorithms access all internal sensors to gather a full set of sensor data.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

It’s easy to use. Everything worked after only a few minutes of effort. I have gotten onto another extensive project, so have not applied it to anything yet, but am looking forward to getting back to it. There are certainly some interesting possibilities here.
I own a bunch of these guys and use them for everything from digital protractors to experimental UAV control.
The breakout is good with decent mounting and the obvious breadboard friendly pins. The ability to change the I2C address is nice too.
This IC isn’t quite deprecated, but it will be soon. Just beware if working on an IMU system that the new variant of this chip is able to actually muster the onboard fusion which may negate your need for an MCU.
This unit is a great deal at its cost. There are a few complaints I have against it but nothing major enough to change my rating by much. The documentation is a bit poorly organized and it was a bit of a headache to get everything hooked up. It is two different IC’s on a single chip. So there are two i2c addresses. One for the magnetometer and one for the gyro/accel. Once I figured that out it was mostly smooth sailing.
I am using this board to collect orientation data for a school quadcopter project of mine. So far, this board has served me very well! I am having one small issue where the yaw and pitch data are nonsensically skewed when the board is rotated past 45 degrees on the y axis, but I am still unsure if this is a hardware problem or a problem with how I am interpreting the DMP raw data.
All in all, a good product for this price!
Reliable, easy to use and a good Reg Map doc. I bought my 1st one some years ago and was great. With the price fall since the MPU-9250 came out it’s a must have.
The documentation and libraries already available about this board are so useful.
