A low-cost, low-power-consumption 2-axis compass module, PNI's preprogrammed CompassPoint™ V2Xe features an onboard microprocessor for true plug-and-play compassing and magnetic field sensing functionality in seismic monitoring, wind direction sensing, and robotics applications. CompassPoint V2Xe provides all-digital compass heading outputs accurate to 1 degree, can be calibrated to account for local magnetic fields, and includes non-volatile memory that retains accurate calibration even when powered down. The V2Xe eliminates the time and expense of building a compass from scratch, making it a perfect solution for high-volume electronics applications as well as robotics and engineering.

Turnkey 2-axis compass...
With low power consumption, high signal/noise immunity under all conditions, and software configurable resolution and field measurement range, the CompassPoint V2Xe is the perfect solution for adding compass heading functionality to virtually any application.
...for every budget.
CompassPoint V2Xe allows designers to bypass the time and expense required to build a 2-axis digital compass from scratch. Advantages include 3 V operation for compatibility with new systems, low power consumption, a small footprint, large signal noise immunity under all conditions, and a large magnetic field dynamic range. Resolution and field measurement range are software configurable for a variety of applications. The measurement is very stable over temperature and inherently free from off set drift. These advantages make the CompassPoint V2Xe the choice for compassing applications that require a high degree of azimuth accuracy, low power consumption, and/or a small package size.
