Crowtail- IMU 10DOF


This is a 10 DOF IMU sensor which is built on MPU-9250 and BMP280, MPU-9250 is a 9-aixs motion tracking device that combines a 3-axis gyroscope, 3-axis accelerometer, 3-axis magnetometer and a Digital Motion Processor (DMP) in a 3*3*1mm package, finally add a barometer- BMP280, so it becomes a 10DOF IMU, it’s smaller in sizes with less power consumption, so use it with mobile phone or aircraft, smart wear devices will be more suitable. User-programmable full-scale range (digital output) and high accuracy of temp/pressure measurement make it meet the ideal for motion tracking and environment monitoring. Its crowtail interface take easy and simple use experience for your Arduino projects.

Model: CRT35038I

Get one now Get one now Get one now

STEP2 Plug Crowtail-Base Shield into Crowduino Uno;
STEP3 Plug Crowtail- IMU 10DOF into I2C port on the Crowtail-Base Shield I Port with Crowtail cable;STEP4 Connect Crowduino Uno to PC via a Mini USB cable.

If we don't have Crowtail Base Shield, We also can directly connect this module to Crowduino Uno as below.


STEP1 Download
STEP2 Configure controller board&communication port
On top of the Arduino IDE, click “Tools>Board>” and select “Arduino Uno” from the available options
Select the COM port that indicates Arduino Uno. Please note that the actual numbers after the “COM” word will vary from computer to computer, so they could be different from the ones shown in the figure. S 2 2.png
STEP3 Install Library: Unzip the file and copy it to the Libraries directory under the Arduino installation directory
STEP4 Open Arduino IDE and load IMU_10DOF_Test:click “File→Examples→IMU10lib_Arduino_Library→IMU_10DOF_Test”
STEP5 Click the Upload.png to upload the code to the Crowduino board
STEP6 After the program is downloaded, open the Serial Monitor of Arduino IDE, set baud rate to 56700,information will be printed show as follow:
