Microduino-10DOF

Microduino-10DOF Microduino-10DOF module use IIC interface to connect with core module and integrates 4 kinds of sensors. MPU6050 uses to 3-axis gyroscope and 3-axis accelerometer, HMC5883L uses to 3-axis compass,BMP085 for temperature and pressure sensor. This module widely used in automation control, such as aeromodelling,self-balancing car.

Features Three kinds of sensors all use I2c interface to connect with core module which save the IO interface, widely used in embedded system; Small, cheap, stackable, opened platfrom; Open source hardware circuit design, compatible with the Arduino IDE development environment for programming; Defines unified interface Microduino specification and contain rich peripheral modules. Set up the quick connection with other Microduino modules and sensors easily and flexibly. 2.54 pitch row female connector for easy integration into breadboard.

Specification Magnetic field intensity sensor：HMC5883L HMC5883L contains the most advanced high-resolution HMC118X series magnetoresistive sensor; Integrated circuit with Honeywell patents, including amplifier, automatic degaussing actuator, offset calibration, 12 bit AD converter with the accuracy of the compass can be controlle in the 1 ° ~ 2 °; Simple I2C serial bus interface. Digital Pressure Sensor：BMP180 BMP180 comprises resistive pressure sensor, AD converter, and a control unit; The control unit includes E2PROM and I2C interfaces. BMP180 transmits uncompensated temperature and pressure values. E2PROM stores 176bit individual standard data, which used for compensation of temperature dependence and the other sensor parameters. Available range: 300hPa to 1100hPa (corresponding sea level -500m to +9000 m) Lowest absolute accuracy can be achieved 0.03hPa UP = pressure data (16 to 19bit) UT = temperature data (0 to 15bit) Triaxial accelerometer + three-axis gyro sensor：MPU6050 It integrates a 3-axis MEMS gyroscope, three-axis MEMS accelerometer, and a scalable digital motion processor DMP (Digital Motion Processor); Digital output for 6 or 9 axis rotation matrix, quaternion, Euler angles format (EulerAngleforma) data fusion algorithms; With 131LSBs / ° / sec sensitivity and whole cell sensing range is ± 250, ± 500, ± 1000 and ± 2000 ° / sec of 3-axis angular velocity sensor (gyroscope); 3-axis accelerometer is programmable control and the range is ± 2g, ± 4g, ± 8g and ± 16g; Reduces the impact of setting given and sensor drift by removing the shaft between the accelerator and the gyro sensitivity, ; The complexity of data fusion algorithms, sensors synchronization, load position sensors can be reduced by useing Digital motion processing (DMP: DigitalMotionProcessing) engine A temperature sensor with digital output; Gyro operational current: 5mA, gyroscope standby current: 5uA; accelerator operation current: 500uA, accelerator power saving mode current: 40uA @ 10Hz up to 400kHz fast mode of I2C.
