I found this in one of my rss feeds:
The MPU-9150™ is the world’s first 9-axis motion tracking device designed for the low power, low cost, and high performance requirements of consumer electronics equipment including smartphones, tablets and wearable sensors.
The MPU-9150™ is actually two chips in one package: the MPU-6050 ( 3-axis gyro / 3-axis accelerometer ), and an AK8975 ( 3-axis digital compass ). They’ve also included what they call a Digital Motion Processor™ (DMP™) which is used to precisely process and ship sensor data over I2C.
It’s pretty small- 4x4x1mm with a 2.4 to 3.34V operating range. So… probably not something you can hook-up directly to a microcontroller. [Via]
