VN-100 SMD

The VN-100 SMD (Surface-Mount Device) is a miniature, surface mount, high-performance Inertial Measurement Unit (IMU) and Attitude Heading Reference System (AHRS). Incorporating the latest MEMS sensor technology, the VN-100 combines 3-axis accelerometers, 3-axis gyros, 3-axis magnetic sensors, a barometric pressure sensor as well as a 32-bit processor into a miniature surface mount module.

Along with providing calibrated sensor measurements, the VN-100 also computes and outputs a real-time, drift free 3D orientation solution that is continuous over the complete 360 degrees of motion.


The VN-100 was the first Attitude and Heading Reference System (AHRS) on the market to offer calibrated, high-performance, industrial grade MEMS sensors and quality sensor fusion algorithms in a single surface mount package. The small size and weight of the VN-100 simplifies sensor integration for new and existing designs. Only a single 3.2 - 5.5 V power supply is required. Communication with the VN-100 is possible using either the serial 3 V TTL (UART) or the Serial Peripheral Interface (SPI). An extensive set of user-selectable registers enable a wide level of customization.

10-Axis MEMS IMU

Utilizing the latest advancements in MEMS technology, the VN-100 incorporates an assortment of inertial sensors, including a 3-axis accelerometer, 3-axis gyroscope, 3-axis magnetometer, and a barometric pressure sensor. The VN-100 has been designed to achieve the highest performance possible by filtering out common error sources, such as sensitivity to supply voltage variations and temperature dependent hysteresis.

To ensure the highest level of accuracy, each VN-100 sensor is individually tested and characterized at room temperature (standard calibration) or over the full operating temperature range (thermal calibration) to determine the bias, sensitivity and cross-axis alignment for each individual component. Calibration coefficients are stored on the device and are fully temperature compensated onboard, in real-time, to ensure high accuracy measurements over the selected operating temperature range.



We provide a wide variety of hardware and software tools that simplify the evaluation and integration of our line of navigation sensors. The Development Kits provide out-of-the-box access to all of the hardware functionality of the VN-100 IMU/AHRS. Our Sensor Explorer graphical user interface provides a powerful tool for evaluation, performance analysis and configuration of VectorNav sensors. Software libraries are also provided to facilitate easy integration with existing platforms. Development kits are available for each of the VN-100 SMD and the VN-100 Rugged.

10-Axis MEMS IMU


The VN-100 SMD (Surface-Mount Device) development board provides easy access to both serial ports on the VN-100. The first serial port is available as a virtual COM port on USB, while the second serial port is available with RS-232 logic levels on a female DB-9 connector.

Access to All Pins

Direct access to all pins on the VN-100 is provided using the 30-pin header for easy prototyping.

Power Options

The VN-100 development board can either be powered by USB, a 5V barrell jack, or directly via the 30-pin header.
