  • DESCRIPTION

    Note: This TinyShield has been discontinued and replaced with the 9-Axis IMU TinyShield

    This TinyShield features the InvenSense MPU-9150™- the world’s first 9-axis MotionTracking 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 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 9 Axis DOF TinyShield incorporates level shifters and a local power supply to ensure proper and safe operation over the entire TinyDuino operating voltage range up to 5V.

      Invensense MPU9150 IMU Specs

      • 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
      • Digital Motion Processing™ (DMP™) engine offloads complex MotionFusion, sensor timing synchronization and gesture detection
      • 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: 10µA at 1Hz, 20µA at 5Hz, 70µA at 20Hz, 140µA at 40Hz
      • Full Chip Idle Mode Supply Current: 8µA
      • On-chip timing generator with ±1% frequency variation over full temperature range
      • 10,000g shock tolerant

        TinyDuino Power Requirements

        • Voltage: 3.0V - 5.5V 
        • Current
          • Gyro 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: 10µA at 1Hz, 20µA at 5Hz, 70µA at 20Hz, 140µA at 40Hz
          • Full Chip Idle Mode Supply Current: 8µA
          • This board can be used with the TinyDuino coin cell option, however the user should power down between readings to minimize the current draw or else battery life will be very short

        Pins Used

        • A5/SCL - I2C Serial Clock line
        • A4/SDA - I2C Serial Data line

        Dimensions

        • 20mm x 20mm (.787 inches x .787 inches)
        • Max Height (from lower bottom TinyShield Connector to upper top TinyShield Connector): 5.11mm (0.201 inches)
        • Weight: 1 gram (.04 ounces)

        Notes

        • You can also use this shield without the TinyDuino – there are 0.1" spaced connections for power, ground, and the two I2C signals along the side of the TinyShield to allow you to connect a different system.
