32-Channel EEG
32-channel EEG acquisition board built around four ADS1299 analog front ends, engineered for ultra-low noise multi-channel neural signal acquisition. Built for OpenHuman.
Project overview
32-channel EEG acquisition board built around four ADS1299 analog front ends, engineered for ultra-low noise multi-channel neural signal acquisition. Built for OpenHuman.
Engineering approach
Medical and biosignal electronics carry tight requirements around noise floor, shielding, and repeatable measurement accuracy. On this board, that translates into a component set built around 8L and 32-Channel ADS1299 AFE, with layout and stack-up decisions driven by signal integrity, low-noise analog front-end layout, and careful grounding to keep biosignal readings clean.
