Compatibility
Fits any microcontroller with an analog input: Arduino Uno, Mega, Nano, ESP32, ESP8266, and Raspberry Pi (with external ADC). Accepts 3.3V or 5V power, with logic levels matching supply voltage. Pair with the standard 3-lead patient cable and disposable electrodes for best results.
Wiring Notes
Connect the module’s OUT pin to an analog input, and LO+ / LO− to digital pins for lead-off alerts. Use the 3‑electrode configuration: right arm (RA), left arm (LA), and left leg (LL). Keep signal leads short to reduce 50 Hz interference.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, works directly with any Arduino board that has an analog pin (Uno, Mega, Nano). Just connect OUT to A0, power to 5V or 3.3V, and read with analogRead().
Do the electrodes come in the box?
Yes, the kit includes a set of adhesive ECG electrodes and the 3.5 mm to snap-lead patient cable.
Can this diagnose heart conditions?
No, it is intended for educational, hobby, and fitness monitoring only. It does not provide medical-grade diagnosis.
