Dual Axis Gyro Module

View Cart

The Dual-Axis Gyro module carries the IDG-500 from InvenSense. The IDG-500 uses complex, high-performance MEMS technology to offer 500°/sec full scale range and 2mV/°/sec sensitivity of rotation, and also includes a patented “Auto Zero” feature for minimizing bias drift over temperature. Because temperature sensing is core to its function, the IDG-500 is also able to read out temperatures from -20 to 85 C. This versatile chip has a number of additional integrated features, such as a 4.5x second gain stage amplifier, as well as built-in low-pass filters.

Even though the IDG-500 is designed to accept a 3V power supply, the board itself is built to be 5V tolerant for most Arduino-based projects. The Dual Axis Gyro module is also equipped with a 3V regulator to provide power out as well, and was designed with hollow center for easy rotational mounting.

Combine this with a JeeNode and/or accelerometer you’ve got a nice portable data sensor for human (or robot) bodies.

The Dual Axis Gyro Module comes assembled, but with (2) 8-pin male headers provided unmounted.
