Product Description
A high-performance 6-axis motion tracking module combining a 3-axis gyroscope and a 3-axis accelerometer on a single chip, ideal for orientation sensing and robotics stability in Arduino and ESP32 projects. Powered by the advanced MPU6050 IC, this GY-521 breakout board features an integrated Digital Motion Processor (DMP) capable of handling complex 6-axis MotionFusion algorithms directly on-chip. This onboard processing frees up your host microcontroller’s processing power by offloading intensive orientation computations. Communicating via a standard two-wire I2C interface, the module delivers highly accurate, low-noise measurements, making it an essential component for self-balancing robots, drone flight controllers, and smart wearable motion trackers.
Pinout / Layout Connections
The module breaks out its communication and power lines via an 8-pin interface header:
VCC Pin: Power supply input, accepts DC +3V to +5V (includes an onboard low-dropout voltage regulator).
GND Pin: Common system ground reference.
SCL Pin: I2C Serial Clock line for timing synchronization.
SDA Pin: I2C Serial Data line for bidirectional telemetry transmission.
XDA Pin: Auxiliary I2C Serial Data line (used to connect external sensors like magnetometers directly to the MPU6050).
XCL Pin: Auxiliary I2C Serial Clock line.
ADO Pin: I2C Address select pin (pull LOW to select address 0x68, pull HIGH to select address 0x69).
INT Pin: Programmable Interrupt output pin to signal the host MCU when data is ready or motion is detected.
Applications
Self-Balancing Robotics: Perfect for dual-wheeled balancing robots, automated stabilizing platforms, and active suspension models.
RC Flight Controllers: Excellent for tracking pitch, roll, and yaw dynamics in DIY drone builds and remote-controlled aircraft.
Immersive Human-Machine Interfaces (HMI): Ideal for gesture control gloves, VR tracking devices, and handheld 3D air mice.
Compatibility
The GY-521 MPU6050 operates over a flexible power range and uses a standard I2C bus, ensuring full compatibility with:
Arduino Board Series (Uno, Mega, Nano, Pro Micro) using standard MPU6050 and wire libraries.
ESP32 and ESP8266 boards (Fully compatible with native 3.3V I2C logic lines).
Raspberry Pi and Raspberry Pi Pico (Ideal for Python-driven spatial telemetry projects).
STM32 and standard 8-bit/32-bit MCUs.
