GY-521 MPU6050 3-Axis Gyroscope and Accelerometer Module

The MPU6050 combines a gyroscope and accelerometer on a single chip with its own onboard digital motion processor, which matters because reading both sensors separately and fusing their data in software is exactly the hard part this chip does internally. The GY-521 board exposes that as a simple I2C device, so a microcontroller reads orientation and acceleration data over the same two wires used for any other I2C sensor.

Both the gyroscope range (up to ±2000 degrees/second) and accelerometer range (up to ±16g) are software-selectable, so the same board suits a slow-moving balancing robot and a project tracking hard impacts without needing different hardware. A 16-bit ADC on each axis gives enough resolution for genuinely smooth motion tracking rather than a jittery approximation.

Common uses are self-balancing robots, drone stabilization prototypes, gesture-control projects, and any build needing to know its own orientation or motion in real time.
