Multi-Channel Biopotential Recorder Kit with ESP32 + LED
Multi-Channel Biopotential Recorder Kit: Capture EMG, ECG, and EEG on 8 Channels with ESP32 & ADS1299
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
For the first time, build a professional-grade, 8-channel biopotential recorder right at your desk. This kit equips you with the TI ADS1299 analog front-end and an ESP32 microcontroller to simultaneously acquire electromyography (EMG), electrocardiography (ECG), and electroencephalography (EEG) signals. Whether you're prototyping a wearable health monitor, analyzing neuromuscular activity for a hackathon, or collecting sleep-study data, this self-contained system streams clean, time-synced data to your PC via Wi-Fi for offline analysis.
What You'll Build
A portable, battery-powered biopotential data acquisition system that records up to eight channels of high-fidelity biosignals. The device snap-connects standard electrodes, digitizes signals with 24-bit resolution, time-stamps each sample using the DS3231 RTC, and logs raw data to a microSD card while simultaneously streaming over Wi-Fi. The 0.96-inch OLED shows real-time signal preview and connection status. You'll have a complete data logger ready for MATLAB, Python, or LabVIEW processing.
What You'll Learn
- Interface the ADS1299 8-channel, 24-bit analog-to-digital converter for low-noise biopotential acquisition
- Configure ESP32 for seamless Wi-Fi data streaming and on-device data logging to microSD
- Implement precise timestamping with the DS3231 real-time clock to synchronize multi-modal biosignals
- Design a portable, battery-powered instrument with a regulated power supply using LM2596 and LiPo charging circuitry

Who This Kit Is For
This advanced kit is built for engineering undergraduates (B.Tech ECE, EEE, Biomedical) and postgraduate researchers at IITs, NITs, VIT, or BITS Pilani tackling biopotential acquisition projects. It's also the perfect foundation for Smart India Hackathon teams developing wearable health monitors or for ATL Tinkering Lab mentors guiding advanced bioelectronics workshops. If you've worked with Arduino or ESP32 before and now need professional-grade biosignal acquisition, this kit bridges the gap.
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.
Can I simultaneously record EMG, ECG, and EEG on all 8 channels?
Yes. The ADS1299 has eight independent channels with programmable gain. The kit includes 16 snap electrodes and gel, allowing you to configure up to eight biosignal inputs in any combination. Our AI companion guides you through channel mapping and electrode placement for common montages.
How do I access the offline analysis data on my PC?
The ESP32 streams raw data via Wi-Fi to a Python script (provided in the build guide), and simultaneously logs to microSD in CSV format. You can process the data with MATLAB, Python, or LabVIEW. The DS3231 RTC ensures each sample is timestamped accurately.
Is this kit suitable for a B.Tech final-year project in biomedical engineering?
Absolutely. The multi-channel biopotential recorder is ideal for projects involving ECG feature extraction, EMG-based gesture control, or EEG alpha/beta analysis. The kit provides hardware and software foundation, while our AI companion helps you tailor the firmware to your specific research goal.
What if I’m new to biopotential circuits?
Our AI companion walks you through every solder joint, electrode connection, and safety precaution. You’ll learn about right-leg drive, common-mode rejection, and filtering as you build. WhatsApp support is available if you need human help.
ADS1299 records EMG, ECG and EEG simultaneously on 8 channels. ESP32 streams to PC for offline analysis.
