3-Space™ Nano IC
The 3-Space™ Nano IC integrates triaxial gyroscope, accelerometer, and magnetometer sensing with onboard QGRAD2 sensor fusion in a 24-pin DFN package. Weighing just 0.01 grams, the chip provides complete AHRS functionality for designs where PCB space and component weight are critical.
Filtered orientation is available at up to 200 Hz, together with raw, corrected, and normalized sensor data. Developers can adjust filtering and oversampling, define reference axes, and communicate via SPI, I2C, or asynchronous serial. A Nano Carrier Board is available to simplifiy PCB integration, as well as a separate evaluation kit providing USB access for bench testing.
