Full orientation sensing. Chip-scale footprint.

When board space is measured in millimeters, most designs settle for a raw IMU and push sensor fusion onto the host processor. The 3-Space™ Nano IC removes that tradeoff. Gyroscope, accelerometer, magnetometer, processing, and orientation filtering all integrated together within one 24-pin DFN package measuring 3.8mm x 5.2mm x 1.1mm and weighing 0.01 grams. Your host receives accurate fully fused orientations, not just a stream of raw data.

Orientation your host doesn’t have to compute

The Nano runs our QGRAD2™ sensor fusion filter onboard, supported by a dynamic confidence algorithm and gradient descent calibration that compensate for sensor noise and error in real time. Filtered orientation is available at up to 200Hz, in absolute terms or relative to a reference you define, and in every format your application could ever need: quaternion, Euler angles, rotation matrix, axis angle, and two-vector. Raw, corrected, and normalized sensor data are also available alongside, so your team keeps full visibility into what the sensor sees.

Adaptable to changing environments

Tunable filtering, oversampling, and orientation error correction let you trade responsiveness against stability for your specific application.

Built for your board, documented for your team

The Nano communicates over SPI, I2C, or asynchronous serial, with a programmable interrupt for event-driven designs. Every sensor function is accessible through our well-documented open protocol, in human-readable ASCII or fast machine-readable binary, with an open source API. Firmware is upgradeable in the field.

The fastest way to start is the 3-Space™ Nano Evaluation Kit: connect over USB, explore every function, and prove out your application before committing to a board layout. For breadboard prototyping or simplified SMT prototyping, the Nano Carrier Board mounts the chip on a larger footprint.

Need more performance?

Still miniature, ten times faster, next generation: the 3-Space™ LX3 is a complete AHRS / IMU / VRU in 16mm x 15mm and 0.9 grams, with fused orientation at up to 2000Hz using QGRAD3™ or Extended Kalman Filtering, ±1° dynamic accuracy, gyro range to ±4000 °/sec, the integrated World Magnetic Model for true-north heading, and USB 2.0 alongside SPI, I2C, and serial.

Nano or LX3? Choosing the right part

The Nano IC is the right choice when:

• PCB space is at an absolute premium
• Lowest possible power consumption is required
• Unit price is the primary design constraint
• An ultra-miniature IC package suits a high-volume embedded design

Choose the 3-Space™ LX3 when your application needs more:

• Higher performance and output rates. Latest-generation v3 firmware and next-generation processing deliver faster, lower-latency orientation, at up to 2000Hz, for stabilization, robotics, closed-loop control, and other applications where fidelity and latency matter.
• Better navigation. An integrated World Magnetic Model and magnetic or true-north heading commands make the LX3 well suited to UAV, USV, UGV, and other navigation applications.
• Newer sensors. Newer-generation MEMS sensors and processing hardware improve overall performance and deliver ±1° dynamic accuracy.
• Power control. Scale power to the moment: low-power when you need it, full performance when you need it.
• Simpler setup. The v3 settings interface dramatically simplifies configuration and deployment.
• A platform that keeps improving. The LX3 platform separates the firmware from the underlying sensing hardware, so firmware updates can keep adding features and performance improvements to your installed base.
• An easy upgrade path. The LX3 keeps a small SMT footprint (16mm x 15mm, 0.9 grams) while delivering substantially greater capability.

For high-g capture and GPS-denied tracking: the 3-Space™ Embedded v3.1 adds auto-selecting dual accelerometers to ±320g, a barometric pressure sensor, and embedded EEPTS pedestrian tracking.
