The 9DOF MPU-9250 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-9250 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-9250 is a System in Package (SiP) that combines two chips: the MPU-6050, which contains a 3-axis gyroscope, and 3-axis accelerometer. The part is offered in a 4x4x1mm LGA package and is upgrade-compatible with the MPU-6050 integrated 6-axis MotionTracking device.
- Tri-Axis angular rate sensor (gyro) with a sensitivity up to 131 LSBs/dps and a full-scale range of ±250, ±500, ±1000, and ±2000dps and integrated 16-bit ADCs
- Tri-Axis accelerometer with a programmable full scale range of ±2g, ±4g, ±8g and ±16g
- 3-axis silicon monolithic Hall-effect magnetic sensor with magnetic concentrator
- VDD Supply voltage range of 2.4V–3.6V
- Digitally programmable low-pass Gyroscope filter
- Gyro operating current: 3.2mA (full power, gyro at all rates)
- Accelerometer normal operating current: 450µA
- Magnetometer normal operating current: 280µA at 8Hz repetition rate
- All Pins Broken Out to Standard 0.1" Spaced Headers
- Detachable mounting holes
The MPU-9250 replaces the popular EOL MPU-9150 and decreases power consumption by 44 percent. According to InvenSense, “Gyro noise performance is 3x better, and compass full-scale range is over 4x better than competitive offerings.” The MPU-9250 uses 16-bit Analog-to-Digital Converters (ADCs) for digitizing all nine axes, making it a very stable 9 Degrees of Freedom board.
