The Compass Module 3-Axis HMC5883L is designed for low-field magnetic sensing with a digital interface. This compact sensor fits into small projects such as UAVs and robot navigation systems.

The sensor converts any magnetic field to a differential voltage output on 3 axes. This voltage shift is the raw digital output value, which can then be used to calculate headings or sense magnetic fields coming from different directions.

Features:

• Measures Earth’s magnetic fields
• 3-axis magnetoresistive sensor
• Wide magnetic field range (+/-8 gauss)
• 1 to 2 degree compass heading accuracy
• Precision in-axis sensitivity and linearity
• Onboard power regulator
• I²C digital Interface
• Fast 160 Hz maximum output rate
• Designed for use with a large variety of microcontrollers with different voltage requirements

Application Notes:

• Auto and personal navigation
• UAV systems
• Robotic navigation
• Location-based services (LBS)

Key Specifications:

• Power Requirements: 2.7 to 6.5 VDC
