Multi-Channel Biopotential Recorder Variant 26 Kit with ESP32 + LED
Multi-Channel Biopotential Recorder Variant 26 Kit with ESP32 + LED — 8-Channel EMG, ECG, EEG Streaming & Offline Analysis
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 8-channel biopotential recorder that simultaneously captures EMG, ECG, and EEG signals. This kit is designed for biomedical engineering students, health-tech researchers, and developers building wearable diagnostic tools or brain-computer interfaces. With the ADS1299’s ultra-low-noise analog front-end and ESP32’s Wi‑Fi, you stream raw biopotential data to a PC for offline processing in MATLAB, Python, or any custom analysis suite.
What You'll Build
By the end of this build, you’ll have a fully functional multi-channel biopotential acquisition system that streams 8 channels of high‑fidelity EMG, ECG, or EEG data to your computer. Use it to record muscle activation patterns, heart rhythms, or brainwave activity, then perform offline filtering, feature extraction, and visualization for your research, final‑year project, or health hackathon prototype.
What You'll Learn
- Configuring the ADS1299 for simultaneous 8‑channel bio‑signal acquisition with programmable gain and data rates
- Interfacing precision peripherals (RTC, microSD, OLED) with the ESP32 over SPI and I2C buses
- Streaming real‑time biopotential data over Wi‑Fi to a PC using a TCP/IP socket or WebSocket protocol
- Offline signal processing with Python (SciPy, MNE) and MATLAB, including filtering, spectral analysis, and plotting

Who This Kit Is For
This advanced kit is ideal for B.Tech ECE/EEE and M.Tech biomedical students working on final‑year or capstone projects, researchers at IITs, NITs, VIT, or BITS Pilani developing health monitoring prototypes, and participants in Smart India Hackathon (health track) or ATL Tinkering Lab mentors pushing the boundaries of wearable tech. If you need a reliable, ready‑to‑assemble biopotential recorder for serious signal acquisition and offline analysis, this kit shortens your development cycle significantly.
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?
Scan the QR code on the box to launch the AI companion, which walks you through each solder joint, wiring step, and firmware setup. You can also reach our support team on WhatsApp for additional troubleshooting.
Can this kit be used for a biomedical hackathon or final‑year project?
Absolutely. The 8‑channel ADS1299 provides research‑grade signal quality. Hackathon teams use it for real‑time health dashboards, and students have submitted it for IEEE‑style papers after performing offline filtering and feature extraction.
Are the gel electrodes and soldering iron actually included?
Yes. The kit includes 16 snap‑style electrode gel pads and a basic soldering iron with solder wire. You can start assembling immediately—no extra trips to the hardware store.
How do I visualize and analyze the data after streaming?
The AI companion provides ready‑to‑run Python scripts and a MATLAB example that capture data over Wi‑Fi, apply a notch filter, and plot all 8 channels. You can adapt them for your own offline analysis pipeline.
ADS1299 records EMG, ECG and EEG simultaneously on 8 channels. ESP32 streams to PC for offline analysis.
