The MPU-6050 combines a 3-axis gyroscope and a 3-axis accelerometer on the same silicon die together with an on-board Digital Motion Processor (DMP) capable of processing complex 9-axis MotionFusion algorithms. This combination does away with the cross-axis alignment problems that can creep up on discrete parts.
This breakout board for the MPU-6050 makes the tiny QFN package easy to work into your project. Every pin you need to get up and running is broken out to 0.1"-pitch through-hole headers, including the auxiliary master I2C bus which allows the MPU-6050 to communicate with external magnetometers and other sensors.
3-Axis Accelerometer/Gyroscope Board Features
- I2C Digital output of 6- or 9-axis MotionFusion data in rotation matrix, quaternion, Euler Angle, or raw data format (when an external magnetometer is connected)
- Input Voltage: 2.3V to 3.4V
- Selectable Solder Jumpers on CLK, FSYNC and AD0
- Tri-Axis angular rate sensor (gyro) with a sensitivity up to 131 LSBs/dps and a full-scale range of ±250, ±500, ±1000, and ±2000 dps
- Tri-Axis accelerometer with a programmable full scale range of ±2g, ±4g, ±8g and ±16g
- Digital Motion Processing (DMP) engine offloads complex MotionFusion, sensor timing synchronization and gesture detection
- Embedded algorithms for run-time bias and compass calibration — no user intervention required
- Digital-output temperature sensor
Usage Considerations The silkscreen contains an error. The Z axis should show the arrow in a counter-clockwise direction.
VLOGIC must be pulled High. You need to connect the VIO pin either to VDD or to another voltage source. The board was designed with VIO disconnected to give you the option of choosing a separate voltage level for the I/Os if need be. If you don't need to use that feature, simply tie VIO to VDD with a jumper or solder connection. The board will be unresponsive if you leave VIO disconnected as shipped.
InvenSense provides details of the MPU-6050's MotionFusion DMP functions only to large-scale developers. The I2Cdevlib site linked below attempts to reverse-engineer the device functions for the benefit of hobbyists, but is in no way complete.
