IMU Viewer
Visualize motion in real time.
The NeuroPawn EXG Visualizer includes a built-in IMU Viewer — see accelerometer, gyroscope, and magnetometer streams live as you move.
Motion sensing
Accelerometer, gyroscope, magnetometer.
9-DOF inertial sensing built right onto the Knight Board. Capture full six-degree-of-freedom motion data alongside your biosignals — on the same device you already use. Use it for head tracking, motion artifact detection, or noise reduction in your EEG pipeline.
Zero new wiring
It's the same board you know.
Same form factor, same connector, same workflow. The IMU variant adds motion data to your existing BrainFlow stream with no additional hardware or setup changes.
Software
BrainFlow and LSL, out of the box.
IMU channels stream natively alongside EEG and biosignal data via BrainFlow and Lab Streaming Layer — no extra drivers or configuration needed.
