M5Stack ECG module 13.2 (AD8232) with cables and pads

ECG is a heart rate monitor (electrocardiogram) unit that can detect the heart rate and output a cardiogram signal. Electrocardiogram (ECG) technology uses an electrocardiograph to record changes in the electrical activity of the heart during each cardiac cycle. This ECG module integrates the AD8232 single-lead heart rate monitoring at the front end. The collected ECG signal is processed by the AD8603 low-pass filter, and the 10-bit ADC (AD7476) performs analog/digital signal input to the STM32, which has a built-in heart rate statistics algorithm for signal analysis. Finally, the processing results are output in the form of serial communication to facilitate the acquisition and display of the main control device. In terms of signal output, it features a front-end/digital full isolation design to enhance equipment stability and safety.
