NeuroPawn Biopotential Kit
Research‑grade EEG
Accessible by design
An 8-channel open-source biosignal platform — no gel, no complexity, no compromise.
The brain of the kit
Knight Board
A custom 8-channel analog front-end with adjustable gain (1–12), hardware-level noise filtering, and USB streaming — housed in a compact enclosure that clips directly into the headset.
Placement freedom
60 node locations.
Every position in the 10–10 international EEG system is accessible. Configure any montage your research demands — no hardware changes, no rewiring.
No gel. No prep.
Dry spike electrodes.
Spring-loaded conductive pins make direct scalp contact through hair. Set up in under a minute. Swap any time for wet, gold-cup, EMG, or ECG contacts.
Precision Accessory
Gold Cup & Ear Clip.
Clinical-grade signal. Same headset, same connector — no modifications.
Placement
The only headset with full 10×10 coverage.
60 node placement locations across the international 10×10 system. Place electrodes anywhere your experiment demands.
Signal integrity
Clean signal starts at the hardware.
Analog common-mode noise cancellation and right leg drive suppress interference before the ADC ever sees the data. 120 dB CMRR.
Versatility
One kit. Five modalities.
EEG, ECG, EMG, EOG, and general EXG — all from the same headset. No hardware swap required.
Software
BrainFlow and LSL, out of the box.
Works natively with BrainFlow and Lab Streaming Layer. Pair with our free cross-platform EXG Visualizer for real-time FFT, filtering, and CSV export.
