What is it?

This is a high-quality MPU6050 motion sensor 6-axis gyroscope/accelerometer breakout board from Kootek. I got a special deal on a closeout and can pass the savings on to you. These boards come sealed in the original anti-static wrapping with header pins ready for soldering onto the board. The GY-521 Breakout Board has the Invensense MPU-6050 front and center, a KB33 voltage regulator, and 2200 Ohm pull-up resistors on the SDA and SDL lines, which are broken out along with power and ground pins, auxiliary I2C lines, an address pin, and an interrupt pin. I have written an Arduino sketch to get the properly-scaled accelerations and rotation rates from the sensors and perform 6 DoF sensor fusion using an open-source Madgwick sensor fusion filter. For more about 6- and 9Dof sensor fusion see here.

Why did you make it?

I purchased these in bulk thinking I would use them for my motion sensing and control applications. However, after I started designing and making my own motion sensor breakout boards, I discovered I no longer had a need for these. I got a good deal on them and would like to pass the savings onto someone who would be able to use them.

What makes it special?

The MPU6050 is one of the first integrated motion sensor that is still very popular with roboticists and quadcopter makers. It is a robust, fairly easy-to-use chip and the sketch makes getting the most out of this chip relatively painless and easy. I've already done the hard work of making the sketch, and Kootek already designed and built these boards. All that is left is to find them a good home and I am offering them at a good price to that end.
