## Description

Compact solution for measuring orientation and movement in space, ideal for robotics, drones and tilt detection. Integrates original MPU-6050 sensor with 3-axis accelerometer and gyroscope, I2C communication for quick connection to Arduino and other microcontrollers, 3V-5V power supply via integrated LDO regulator, durable PCB with gold finish for stable contacts.
The GY-521 module is a compact and efficient solution for measuring movements and orientation in space, integrating the MPU-6050 sensor, which combines a 3-axis accelerometer and gyroscope. This module is ideal for applications in robotics, drones, navigation systems, tilt detection, or any project that requires precise measurements of acceleration and rotation.
With a standard I²C interface and an integrated voltage regulator, the module is easy to connect to Arduino boards and other microcontrollers. The high-quality PCB, with immersion gold finish, ensures increased durability and reliable electrical contacts.
The module uses the original IC (more expensive compared to the compatible version).
