A low-cost, low-power-consumption 2-axis compass module, PNI's preprogrammed V2Xe features an onboard microprocessor for true plug-and-play compassing. The V2Xe provides all-digital compass heading outputs accurate to 1 degree when level, can be calibrated to account for local magnetic fields, and includes non-volatile memory that retains accurate calibration even after being powered down. The V2Xe eliminates the time and expense of building a compass from scratch, making it a perfect solution for quick engineering prototyping, hobby projects, and the orientation of static instruments, such as weather stations and antenna towers.

V2Xe allows designers to bypass the time and expense required to build a 2-axis digital compass from scratch. Advantages include 3 V operation, low power consumption, a small footprint, large signal-to-noise immunity, 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 V2Xe the choice for level or static compassing applications that require a high degree of azimuth accuracy, low power consumption, and/or a small package size.
