Wireless EEG System: Open BCI Kit with Arduino Nano 33 BLE
Stream Brain Activity Wirelessly: Open BCI Kit with Arduino Nano 33 BLE
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Construct a professional-grade wireless EEG headset that captures eight channels of brain activity at 250 samples per second. The ADS1299 analog front-end feeds clean biopotential signals to the Arduino Nano 33 BLE, which streams them over Bluetooth to the OpenBCI GUI. You get a complete, isolator-protected neural interface for research, neurofeedback experiments, and brain-computer interface prototyping-no scattered parts sourcing, no guesswork.
What You'll Build
You'll assemble a battery-powered, galvanically isolated EEG acquisition system that fits into a custom cap. The onboard microSD module logs timestamped data via the DS3231 real-time clock, while the BLE stream lets you watch brainwaves in real time on your PC. The kit includes a pre-assembled ADS1299 front-end board, so you focus on integrating electrodes, power management, and firmware, not on debugging delicate SMD soldering.
What You'll Learn
- Acquiring high-impedance EEG signals with gel electrodes and minimizing 50Hz noise
- Configuring the ADS1299 analog front-end over SPI for gain, sampling rate, and channel mapping
- Implementing galvanic isolation with the ADUM4150 to meet safety requirements for human connection
- Streaming 8-channel neural data wirelessly via Arduino Nano 33 BLE and visualizing in OpenBCI GUI

Who This Kit Is For
This kit is designed for B.Tech and M.Tech students in ECE, biomedical engineering, or signal processing who need a reliable final-year project platform. Neurohackers at events like Smart India Hackathon will have a pre-integrated neural front-end ready to prototype BCIs. Researchers at IITs, NITs, VIT, or BITS Pilani prototyping assistive technologies or brain-computer interfaces will find the isolated, wireless design immediately useful.
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?
Your AI build companion covers every step from soldering electrode snaps to ADS1299 register settings. For edge cases, WhatsApp support from our Bengaluru team replies within hours.
Do I need prior biosignal experience?
Yes, this is an advanced kit. You should be comfortable with Arduino IDE and SPI communication. The AI guide and pre-flashed firmware help you focus on signal quality rather than low-level driver code.
Can I use this for medical-grade EEG diagnosis?
No, this kit is for educational and research prototyping. It is not a clinical device, and the electrodes are not medical grade. Always follow institutional ethics guidelines for human subjects.
What software is compatible with the streamed data?
The Arduino Nano 33 BLE runs firmware that sends data in OpenBCI's native format. You can visualize it in the free OpenBCI GUI, or write Python scripts for offline analysis using the included microSD logs and RTC timestamps.
ADS1299 EEG front end on Arduino Nano 33 BLE streams 8-channel 250sps neural data wirelessly to OpenBCI GUI.
