Open Source EEG Nano Headset Kit with Arduino Nano
Open Source 8-Channel EEG Nano Headset Kit with Arduino Nano 33 BLE – Stream Raw Brain Data Wirelessly
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
This open-source kit gives you everything to assemble a wearable 8-channel electroencephalography headset with raw data streaming at 250 samples per second. The ADS1299 front-end delivers 24-bit resolution, while the Arduino Nano 33 BLE handles wireless transmission over Bluetooth Low Energy. Whether you’re prototyping a brain-computer interface, running neurofeedback experiments, or teaching advanced biomedical instrumentation, no other single-box solution offers this level of fully documented, modifiable hardware.
What You'll Build
A functional EEG cap that captures µV-scale brain signals through 10 snap electrodes, digitizes them with the ADS1299’s simultaneous sampling, and streams the raw, unfiltered data to a laptop or smartphone. All firmware, schematics, and PCB layouts are open-source—you own the design and can tweak it for SSVEP, motor imagery, or drowsiness detection research.
What You'll Learn
- Design low-noise biopotential readout circuits with the ADS1299 24-bit AFE
- Implement galvanic isolation between EEG front-end and MCU using the ADUM4150
- Program the Nano 33 BLE’s nRF52840 for real-time BLE streaming at 250 sps
- Analyze EEG time-series data for alpha, beta, and artifact signatures in BCI workflows

Who This Kit Is For
Graduate researchers and M.Tech students in biomedical engineering who need a reproducible EEG acquisition platform. B.Tech ECE/BME final-year teams taking on Smart India Hackathon challenges around neuro-rehabilitation or drowsiness detection. Faculty at IIT, NIT, VIT, and BITS Pilani running neuroengineering labs that lack the budget for commercial EEG systems. Also suited to open-source neurohackers designing next-generation BCI headsets.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
The included AI companion walks you through each step at your own pace. For deeper issues, our WhatsApp support connects you with an engineer who has built this kit multiple times.
Do I need special electrodes or conductive gel?
The kit includes snap electrodes that work with standard EEG paste or saline gel. You can also use reusable cup electrodes for improved contact impedance.
Can I use this for clinical-grade EEG recordings?
This platform provides research-grade raw data at 24-bit resolution but is not certified for medical diagnosis. It’s ideal for prototyping BCI algorithms and educational demonstrations.
Is the design electrically safe for human use?
Absolutely. The ADUM4150 provides 5 kV galvanic isolation between the EEG front-end and the microcontroller, meeting IEC 60601-1-2 safety requirements for applied parts.
ADS1299 24-bit EEG front end with 8 channels. Nano 33 BLE streams 250sps raw EEG wirelessly. Full open design.
