Why PiEEG-8.
Research-Grade 24-Bit Signal Path
Built around the industry-standard ADS1299 biopotential ADC with programmable gain (1× to 24×), hardware lead-off detection, and ultra-low input-referred noise.
Direct SPI to Python in Minutes
Reads real-time EEG, EMG, and ECG streams straight on the Raspberry Pi without USB dongles or proprietary middleware. Stream to PiEEG Server, LabStreamingLayer, or MNE-Python.
Cited in Peer-Reviewed Research
Trusted by university teaching labs and BCI researchers worldwide as the most accessible entry point into open-source neurotechnology.
