The 3-Space™ LX3 provides nine-axis inertial sensing and onboard orientation processing in a 16 x 15 x 1.7 mm module weighing 0.9 grams. Its compact surface-mount form factor is ideal for UAVs and other unmanned platforms with limited board space™.
QGRAD3 and selectable Extended Kalman filtering deliver update rates up to 2,000 Hz. The integrated World Magnetic Model provides heading referenced to true, magnetic, or grid north. Developers can tune filtering, oversampling, and orientation error correction, with configurable power modes for different operating requirements.
USB, SPI, I2C, and asynchronous serial interfaces provide flexible host connections. Castellated edge pads simplify PCB integration, and a USB evaluation kit is available for testing the sensor and its interfaces before production.
