Cerelog Inc.

Cerelog develops affordable, high-precision biosensing hardware for researchers, engineers, and DIY neuroscience enthusiasts. Its ESP-EEG circuit boards are designed for brain-computer interface (BCI) development and the collection of electrophysiological signals, including EEG, EMG, ECG, and EOG. The boards use Texas Instruments’ 24-bit ADS1299 analog-to-digital converter and an ESP32 microcontroller, with USB-C, Bluetooth Low Energy, Wi-Fi, and onboard LiPo charging for flexible data streaming.

Cerelog offers 8-channel and 16-channel versions, with listed prices starting at $389.99. The company highlights a closed-loop active bias design intended to reduce noise and movement artifacts. Data can be used with BrainFlow, a customized version of the OpenBCI GUI, and Lab Streaming Layer, supporting research workflows and custom software development. Applications described include BCI research, neurofeedback, cognitive studies, biometric data logging, and EMG-based projects such as robotic hand control. Cerelog also provides GitHub code for its robotic hand demonstration and offers electronic design services and custom hardware. The ESP-EEG is presented as a research instrument, not a medical device.
