EEGFrontier
A compact open-source EEG board using ADS1299. 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. The goal was to design a low-cost board that works with dry electrodes while exposing the full EEG signal chain — no abstractions, no closed firmware.
