M5Stack ECG Module (with Cables and Pads)

The M5Stack ECG Module is a heart rate and ECG monitoring module with built-in signal processing and heart rate analysis, designed for capturing and displaying real-time cardiac waveform data safely and reliably. The M5Stack ECG Module is a heart rate measurement module capable of being used for human heart rate statistics and ECG waveform generation. Electrocardiography (ECG) is a technique that uses an electrocardiograph to record the electrical activity of the heart during each cardiac cycle from the body surface. On the signal acquisition side, the Module13.2 ECG integrates the AD8232 single-lead heart rate monitoring front end. The collected ECG signal is processed through the AD8603 low-pass filter, then fed into a 10-bit ADC (AD7476) for analogue-to-digital conversion and input into an STM32 (which has a built-in heart rate statistics algorithm) for signal analysis. Finally, the processing results are output in serial communication format, making it easy for the host device to acquire and display the data. In terms of signal output, it adopts a full isolation design between the front-end and the digital part to enhance stability and safety. Power Supply Note - This product only supports 5V power input. Please strictly follow this power input standard when using the product to avoid damage to the device or potential injury.
