Description
The AD8232 ECG Heart Rate Monitor Module is a compact analog front-end board designed to measure and condition cardiac electrical signals. Based on the AD8232 IC, it integrates signal amplification, filtering, and leads-off detection to generate a stable analog ECG output. The module operates at 3.3V DC and features a 3.5 mm jack for standard biomedical electrode pads. Built for reliable signal acquisition with reduced motion artifacts, it is suitable for biomedical experiments, wearable prototypes, and educational ECG monitoring systems.
