In this work an acquisition module of EEG (Electroencephalographic) signals was developed, oriented to the later construction of a brain computer interface which could allows offer aid and/or rehabilitation therapy to people with motor and/or communication disabilities. The study of these brain computer interfaces is not new, has around 2 decades of investigation. For the implementation of these systems is basically needed 3 stages: An EEG signals acquisition, a signal processing stage, so that it is finally possible to extract specific signal features, according to certain stimuli and finally, features are translated into commands that operate a device like the movement of wheelchairs, prosthesis of amputated members, movement of images or even selection of letters to form words in screen. The acquisition systems used in the study of Brain computer interfaces are usually expensive for that reason this work is centralized in the development of the EEG acquisition stage which allows the beginning of the investigation in this area in our country
