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 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. All Pins Broken Out to Standard 0.1" Spaced Headers Solder Jumper for Switching LSB of I2C Address 描述: 9自由度的MPU9150是世界上第一个9-轴的运动跟踪MEMS器件，为消费类电子设备包括智能手机平板电脑可穿戴设备而设计的低功耗，低价格高性能要求而设计的。猜猜是什么。你可以玩转它了。这个模块使得用Invensense MPU9150芯片，通过将所有的引脚分为每一个标准的0.1mil间距的排插，很容易设计原型。这个板子提供了I2C的上拉电阻和一个焊接跳帽以改变I2C器件的地址。 MPU9150是要给在封装内的系统，包含了两个芯片：MPU6050(包含3-轴的陀螺仪，3-轴的加速器和一个板上的数字运动处理器，能够处理复杂的运动整合算法)；AK8975 ，3-轴的数字指南针。这部分已经集成了6轴的运动整理算法，能够连接所有内部的传感器以整合一套完整的传感器数据。特性：3轴的角度速率传感器（陀螺仪），灵敏度达到 131 LSBs/dps，以及一个完整幅度的范围（±250, ±500, ±1000, and ±2000dps）拥有可编程的完整幅度（ ±2g, ±4g, ±8g and ±16g）的加速度计；拥有完整幅度（±1200µT）三周指南针削减的设置效应以及传感器漂移，通过消除在加速度计陀螺仪和指南针的板级的跨轴排列错误 VDD电源范围 2.4V–3.46V; VLOGIC范围 1.8V±5% 或者VDD 陀螺仪工作电流：3.6mA(满电，在各个速率) 陀螺仪+加速度计工作电流：3.8mA(满电，陀螺仪工作在完整速率，加速度计在1kHZ的采样率) 陀螺仪+加速度计+指南针+数字运动处理器工作电流：4.25mA(满电，陀螺仪工作在满频率，加速度计工作在1KHz的采样率，指南针工作在8Hz的采样率) 加速度计低功耗模式工作电流：在1Hz 10uA, 在5Hz20uA ,在20Hz70uA ,在40Hz 140uA . 整个芯片休眠模式电流：8uA 400KHz快速模式，IC串口主机接口芯片级的始终产生器在满温度范围内的1%频率变化 10000g 抗击能力板级的I2C上拉电阻所有引脚都引出到标注的1''的控制π插跳帽用于转换I2C地址的最低位 mpu-9150_breakout SCH mpu-9150_breakout PCB EasyEDA项目链接： https://easyeda.com/oshw/9_Degrees_of_Freedom_Breakout_MPU_9150_Open_hardware-OJf9rlDxP EasyEDA链接： https://easyeda.com 0
