M5Stack ECG module 13.2 (AD8232) with cables and pads

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