Description
Product Overview
The GY-50 L3G4200D 3-Axis Gyroscope Module is a high-performance digital angular rate sensor designed for measuring rotational velocity along the X (Pitch), Y (Roll), and Z (Yaw) axes . Based on STMicroelectronics’ advanced MEMS (Micro-Electro-Mechanical Systems) technology, this module provides precise, drift-resistant measurements for motion tracking and stabilization applications.
The L3G4200D sensor features an ultra-stable 16-bit rate-value data output, offering three user-selectable full-scale ranges of ±250, ±500, or ±2000 degrees per second (dps) . This flexibility allows you to optimize sensitivity for specific applications—from slow human motion tracking to high-speed robotics and drone flight control.
With a wide operating voltage range of 2.4V to 3.6V and low current consumption of just 6.1mA, the GY-50 module is designed for low-power applications . The breakout board also includes an onboard 3.3V voltage regulator, making it compatible with both 3.3V and 5V microcontrollers like Arduino, ESP32, and Raspberry Pi.
The sensor features an embedded temperature sensor for drift compensation, adjustable bandwidth from 100Hz to 800Hz, and supports both I2C and SPI digital interfaces for flexible communication . Whether you’re building a self-balancing robot, a quadcopter flight controller, a VR headset, or a vehicle stability system, the GY-50 L3G4200D module delivers accurate, reliable angular velocity data.
