PiEEG provides open-source biosignal acquisition hardware for EEG-based research, education, and BCI prototyping. Its products are built around Raspberry Pi-compatible boards and are aimed at users who need low-cost access to neural and physiological signal recording.

The platform supports EEG, EMG, ECG, and EOG acquisition, with multi-channel hardware, electrode accessories, SDKs, documentation, and real-time data workflows. This makes it usable for brain-signal recording, signal processing, experimental device control, and classroom or maker-led neuroscience projects.

PiEEG primarily serves researchers, students, educators, engineers, and developers working outside high-cost clinical or laboratory hardware stacks. Its role in the market is as an accessible neurotechnology infrastructure layer for building and testing non-invasive EEG systems.
