Product Description

This electronic compass provides magnetic field and acceleration measurements in 3 dimensions. Together these readings provide heading information and can be used as a heading-orientation sensor (electronic compass). The readings are accessed with an I2C interface which is compatible with 3.3V and 5V systems. The module can also provide information on orientation (X,Y, and Z axis). This product is provided as open-source hardware with all design files available for use, re-use, or modification.

Module documentation and application info are available to get you started right away. This is open source hardware, all design files are available.

  • Perfect for mobile systems in need of heading and orientation feedback
  • 3D magnetometer and 3D accelerometer in one package
  • Internal interrupts can programmed for freefall or orientation
  • 3.3-5VDC operation
  • small footprint - 0.7"x1.0"x0.25" (9-pin SIP footprint)
  • comes with solderable header for breadboarding, or may be surface mounted/wired
  • ROHS compliant
