BrainFlow Compatible for Powerful Data Analysis

This board is fully compatible with BrainFlow, the industry-standard open-source library for acquiring and processing biosignals. This integration provides a unified, developer-friendly API to stream data directly into Python, C++, Java, and more, unlocking powerful tools for real-time analysis, signal processing, and BCI development.

Advanced Signal Integrity & Features

Active Bias Drive for Superior Noise Cancellation

The onboard bias probe actively works to cancel common-mode interference from sources like mains hum (50/60Hz noise). By feeding an inverted common-mode signal back to the user, it dramatically improves signal quality, allowing for clean, DC-coupled data acquisition in challenging environments. This is a critical feature for high-fidelity research that many other boards lack.

High-Fidelity ADS1299 ADC

At its core, the board utilizes a research-grade ADC capable of resolving signals down to 10µV peak-to-peak (1-50Hz). While real-world performance is subject to environmental noise and setup, this high-precision foundation ensures you capture the most subtle neural signals.

Flexible Electrode Montage Configuration

By default, the board operates in a sequential montage. However, it supports a referential montage by utilizing the SRB1 pin on the ADC. This mode measures each electrode against a single common reference. If you require this configuration, please contact us before ordering for a firmware adjustment, or we can provide instructions for you to perform the modification.

Required & Recommended Accessories

The following items are not included but are required for a full setup. These are links to third-party vendors.

EEG Electrode Cap Kit

Required

A professional electrode cap is necessary for placing electrodes on the scalp. This is a recommended third-party option.

View Cap Kit

We are not affiliated with this vendor.

Touch-Proof Adapters

Required

These adapters are essential to connect the electrode cap to the Cerelog board. You must purchase two sets for a full 8-channel differential setup.
