From the project
EEGFrontier is an open-source EEG device designed to measure focus and attention during study using real brain signals. It uses a custom-built PCB with a professional EEG analog front-end to capture raw EEG data and stream it in real time to a computer via USB.
EEGFrontier V1 is a compact EEG acquisition board built around the ADS1299-4PAGR and a Seeed XIAO RP2040.
