AD8232 ECG Module Heart Rate Monitor Kit

The AD8232 is a single lead heart rate monitor module designed to measure the electrical activity of the heart and output it as an analog ECG (Electrocardiogram) signal. Based on Analog Devices’ AD8232 IC, it acts as an integrated signal conditioning block that extracts, amplifies, and filters small biopotential signals even in noisy conditions such as those caused by body movement or remote electrode placement. The module breaks out 9 connections including OUTPUT, 3.3V, GND, SDN, LO+ and LO- — making it easy to interface with Arduino, ESP32, STM32, or Raspberry Pi via analog input. Includes built-in leads-off detection, shutdown pin, and LED indicator. The kit comes complete with the main PCB, 3-lead ECG cable, and disposable electrode pads for immediate use.
