The 3-Space™ LX3 combines onboard orientation processing with nine-axis inertial sensing in a compact surface-mount module. Measuring 16 x 15 x 1.7 mm and weighing 0.9 grams, it is ideal for space-constrained defense electronics.
Update rates reach 2,000 Hz with QGRAD3 or selectable Extended Kalman filtering. The integrated World Magnetic Model delivers true, magnetic, or grid north heading. Adjustable filtering, oversampling, orientation error correction, and configurable power modes allow the sensor response to be matched to operating requirements.
Castellated edge pads simplify board integration, with USB, SPI, I2C, and asynchronous serial connections for host processors. A USB evaluation kit provides access to the sensor and its interfaces during development.
