EEG Data Acquisition Interface

Project overview

Single ADS1299 EEG front-end development board, designed to be driven externally by an Arduino or ESP32 host for rapid prototyping of biosignal acquisition firmware.

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 1x ADS1299 and Dev Board, with layout and stack-up decisions driven by signal integrity, low-noise analog front-end layout, and careful grounding to keep biosignal readings clean.

Technical specification

Engineering focus

This portfolio project demonstrates CircuitNexa's electronics engineering and PCB design work in the medical devices space. The design shown here is part of a broader portfolio spanning schematic capture, PCB layout, embedded firmware, prototyping, and support through to manufacturing.
