From the project
Precision Biopotential Analog Front-End (AFE) for ECG/EMG/EEG | CMRR >100 dB | Driven Right Leg (DRL) Active Feedback | KiCad 8 & Production Gerbers
UniPa BioAmp Pro is an open-source, laboratory-grade, low-noise Biopotential Analog Front-End (AFE) engineered in KiCad 8. Designed for recording electrophysiological biopotentials (ECG, EMG, EEG, EOG), it resolves the primary physical challenge of biological measurements: extracting microvolt-level differential biosignals ($\sim 10\,\mu ext{V} - 5\, ext{mV}$) in the presence of severe common-mode environmental interference (up to several volts of 50/60 Hz mains displacement current).
