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. Features: 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 Tri-Axis accelerometer with a programmable full scale range of ±2g, ±4g, ±8g and ±16g Tri-axis compass with a full scale range of ±1200µT Reduced settling effects and sensor drift by elimination of board-level cross-axis alignment errors between accelerometer, gyroscope, and compass VDD Supply voltage range of 2.4V–3.46V; VLOGIC of 1.8V±5% or VDD Gyro operating current: 3.6mA (full power, gyro at all rates) Gyro + Accel operating current: 3.8mA (full power, gyro at all rates, accel at 1kHz sample rate) Gyro + Accel + Compass + DMP operating current: 4.25mA (full power, gyro at all rates, accel at 1kHz sample rate, compass at 8Hz rate) Accel low power mode operating current: 10uA at 1Hz, 20uA at 5Hz, 70uA at 20Hz, 140uA at 40Hz Full Chip Idle Mode Supply Current: 8µA 400kHz Fast Mode I²C serial host interface On-chip timing generator with ±1% frequency variation over full temperature range 10,000g shock tolerant I2C Pullup Resistors populated on board.
