GY 271 3 Axis Compass Magnetometer Sensor Module 3-5V IIC

Description

Product Overview

The GY 271 sensor module is a compact three‑axis electronic compass designed for precision navigation in a variety of electronic projects. Built around a high‑performance magnetometer chip, the module operates on a flexible 3 to 5 V supply, making it compatible with most microcontroller platforms. Its immersion‑gold plated PCB ensures excellent solderability and long‑term reliability, while the standard IIC interface simplifies wiring and software integration. The module measures magnetic fields from ±1.3 Gauss up to ±8 Gauss, providing accurate heading information even in environments with moderate magnetic interference.

Physical dimensions of 0.55 × 0.55 × 0.16 inches and a weight of just 0.32 oz allow the GY 271 to fit into tight spaces on drones, robotic arms, and handheld devices. The robust construction includes a protective epoxy coating that guards the delicate circuitry against moisture and dust, extending the module’s operational lifespan in outdoor and industrial settings.

Usage

Designed for developers and engineers, the GY 271 excels in applications where accurate orientation data is critical. It is commonly used in unmanned aerial vehicles (UAVs) for flight stabilization, in autonomous ground robots for path planning, and in wearable navigation devices for outdoor enthusiasts. The module’s low power consumption makes it ideal for battery‑operated systems, while its IIC communication protocol enables seamless integration with popular development boards such as Arduino, Raspberry Pi, and ESP32.

In addition to aerospace and robotics, the GY 271 can be employed in marine navigation equipment, smart agriculture tools, and IoT sensors that require directional awareness. Its ability to operate across a wide voltage range means it can be powered directly from solar panels or regulated power supplies without additional conversion circuitry.
