I mew, you mew we all mew for IMU! The MPU-6050 is what we call "an oldie but goodie" - this popular triple-axis accelerometer plus gyro combo has been a staple of electronic projects for years, and we've finally gotten around to making a breakout for it!
Inside are two sensors, one is a classic 3-axis accelerometer, which can tell you which direction is down towards the Earth (by measuring gravity). The other is a gyroscope that can sense how fast the board is being twisted around. By combining this data you can tell how your project is moving through space
We based this breakout on the popular sensor, the MPU-6050. This compact sensor uses I2C to communicate, and it's very easy to use. Simply download our library and connect the SCL pin to your I2C clock pin, and SDA pin to your I2C data pin and upload our test program to read out accelerometer and gyroscoping data.
