From the project

EEG Acquisition board software, PCB design files and documentation.

The project contained in this repository is a 4-channel prototype board produced in the development of a PCB to acquire EEG signals. It contains an instrumentation amplifier, a notch filter and an anti aliasing filter. It is designed to be sampled either in a lab with the help of an oscilloscope or with a computer through a Teensy 3.2 microcontroller development board. As well, a signal visualization software can analyze the signal coming from this board.
