Arduino Triple-Axis Digital Output Gyro Sensor ITG-3205 Module

Arduino Triple-Axis Digital Output Gyro Sensor ITG-3205 Module

This is a breakout board for InvenSense's ITG-3205, a groundbreaking triple-axis, digital output gyroscope.The ITG-3205 is the world’s first single-chip, digital-output, 3-axis MEMS gyro IC optimized for gaming, 3D mice, and 3D remote control applications. The part features enhanced bias and sensitivity temperature stability, reducing the need for user calibration. Low frequency noise is lower than previous generation devices, simplifying application development and making for more-responsive remote controls.

The ITG-3205 features three 16-bit analog-to-digital converters (ADCs) for digitizing the gyro outputs, a user-selectable internal low-pass filter bandwidth, and a Fast-Mode I2C (400kHz) interface. Additional features include an embedded temperature sensor and a 2% accurate internal oscillator. This breakthrough in gyroscope technology provides a dramatic 67% package size reduction, delivers a 50% power reduction, and has inherent cost advantages compared to competing multi-chip gyro solutions.

By leveraging its patented and volume-proven Nasiri-Fabrication platform, which integrates MEMS wafers with companion CMOS electronics through wafer-level bonding, InvenSense has driven the ITG-3205 package size down to a revolutionary footprint of 4x4x0.9mm (QFN), while providing the highest performance, lowest noise, and the lowest cost semiconductor packaging required for handheld consumer electronic devices. The part features a robust 10,000g
shock tolerance, as required by portable consumer equipment.

For power supply flexibility, the ITG-3205 has a separate VLOGIC reference pin, in addition to its analog supply pin, VDD, which sets the logic levels of its I2C interface. The VLOGIC voltage may be anywhere from 1.71V min to VDD max.
 
Features:
• Digital-output X-, Y-, and Z-Axis angular rate sensors (gyros) on one integrated circuit
• Digitally-programmable low-pass filter
• Low 6.5mA operating current consumption for long battery life
• Wide VDD supply voltage range of 2.1V to 3.6V
• Standby current: 5μA
• Digital-output temperature sensor
• Fast Mode I2C (400kHz) serial interface
• Optional external clock inputs of 32.768kHz or 19.2MHz to synchronize with system clock
• Pins broken out to a breadboard friendly 7-pin 0.1" pitch header

so does this item measure orientation, or angular acceleration?
 Sloperdude 1427 points
Since it's a gyro, angular acceleration.
 H3nkz 2 points
It measures angular velocity.

Hi, I have been trying to read from this device since yesterday, but I am receiving no results. Following are my connections: (gyro **> Arduino mega) SCA **> SCL* SDA **> SDA* CLK **> GND* INT **> **-* GND **> GND* VIO **> 3.3v* VDD **> 3.3v* address of gyro:0x69* Please let me know what is it that i am doing wrong?

Good day, please help with advice Designed radio-controlled model helicopter carrying capacity of 15 kg, with a jet-driven rotor (propeller - impeller). Support system-1 blade, counterweight is a motor with impeller and battery. control rotor by means servoflap (installed on the blade), controlled by a standard machine radiopravleniya (strong and fast). Receiving part of the 2.4 GHz radio equipment rotates with the blade, the controller, the pilot on the ground. task: how to mix the signal from the position of the rotating blade and azimuth control pulse from the transmitter? Probably need a digital mixer from the encoder (ie digital, with a magnet), and from the receiver to the machine. How this can be done, or can have a simpler solution?

I understand what you are trying....the pulse-jet tipped helicopters in the past history provide lift without yaw torque requiring tail rotor anti-torque... your problem will be the speed and velocity changes of the rotor affecting this gyro unit will be too fast for the units refresh rate. you should find simple 1 channel means of communication to speed control from fuselage mounted controller/gyro unit (this) connected to your radio (also fuselage mounted) -via- infrared , short radio , or other means of getting the simple 1 channel command to each tip-mounted jet engine. Then, control the blades pitch just like regular helicopter -via- conventional rotorhead and swashplate movements... now you have me thinking about building something similar, LOL hope this helps im an inventor too.

Our best friend google: "arduino ITG-3205 library", and U're lucky *) PS. The I2C addresse is 0x69

to Hobbyking, can you provide GPS Compass in one module with digital output like this? very useful for plug and play DIY multicopter, as the compass is sometimes need to be far from power distribution. Same as DJI or other pricey multirotor FC,.. Hwo's with me?

The only other source for something like this was sparkfun, where you paid I think around 50 dollars. WOOOO
 sirbow2 14 points
Yep! good for MWC especially!
 benybee 36 points
damn yes! that's what i mean.. where is admin?
 un4seen 62 points
Actually, there are many other sources for IMUs besides Sparkfun. I got my MPU6050 IMU for 9.84$ with free shipping. It would be great if Hobbyking could stock on some more advanced IMUs, preferably 6DOF or 9DOF, preferably with the MPU6050 and HMC5883L (magnetometer). The 3205 is kinda outdated now.

Works fine, although the I2C interface is a bit of a pain. Doesn't seem to mind 5V (and the specification seems to sort of allow voltages up to 6V), but your mileage may vary.
