Description

The Compass Sensor HMC5883L HW-127 is a high-precision 3-axis digital magnetometer module designed to provide accurate heading and magnetic field measurements. This Compass Sensor HMC5883L HW-127 communicates through the I2C protocol, making it simple to interface with popular development boards such as Arduino, ESP32, and STM32. Because it supports 3–5V input and includes onboard logic level compatibility, it works safely with both 3.3V and 5V microcontrollers. The module measures magnetic fields in the range of ±1.3 to 8 Gauss, allowing developers to calculate direction, detect orientation, and build navigation systems efficiently. Moreover, its compact HW-127 form factor makes it ideal for drones, robotics, and portable embedded systems. Featured By RoboticsBD.
