Abstract	The search for simple yet precise electroencephalogram (EEG) recording systems has been long desired by researchers in the psychophysiology field. During the last two decades, the advancement of instrumentation amplifiers and microcontrollers has provided the adequate tools for the task. In this paper the design of a portable embedded system capable of recording up to 128 EEG electrodes simultaneously is presented. EEG records are stored in a standard SD flash card and can be transmitted to a host PC with a Bluetooth module. The main features of this device are portability, low power consumption, scalability, and low noise among others. The implemented device may allow psychophysiology researchers to perform non-invasive experiments, where individuals are not tied with an uncomfortable group of cables to amplifiers and test equipment.
