“…The first system of the family is formed by two boards: the first, a small and light transmitter is suitable for biofeedback and BCI applications, and is in charge of the acquisition, digitalization and transmission of data; the second, a USB receiver, is connected to a host computer for display, storage and processing of the signals. This device is an updated version of the Wireless Neuro Boards presented in [22], improving 60 Hz/50 Hz noise isolation and providing more flexibility for the electrode configuration. Improvements were done by modifying all the connectors of the transmitter board and adding some components for the selection of reference and bias electrode, as explained in the previous section.…”

Electroencephalogram (EEG) acquisition systems are widely used as diagnostic and research tools. This document shows the implementation of a reconfigurable family of three affordable 8-channels, 24 bits of resolution, EEG acquisition systems intended for a wide variety of research purposes. The three devices offer a modular design and upgradability, permitting changes in the firmware and software. Due to the nature of the Analog Front-End (AFE) used, no high-pass analog filters were implemented, allowing the capture of very low frequency components. Two systems of the family, called "RF-Brain" and "Bluetooth-Brain", were designed to be light and wireless, planned for experimentation where movement of the subject cannot be restricted. The sample rate in these systems can be configured up to 2000 samples per second (SPS) for the RF-Brain and 250 SPS for the Bluetooth-Brain when the 8 channels are used. If fewer channels are required, the sampling frequency can be higher (up to 4 kSPS or 2 kSPS for 1 channel for RF-Brain and Bluetooth-Brain respectively). The third system, named "USB-Brain", is a wired device designed for purposes requiring high sampling frequency acquisition and general purpose ports, with sampling rates up to 4 kSPS.
