What it is
The AD8232 ECG Module - Heart Rate & ECG Monitoring Sensor Kit is a compact biopotential sensor built around the AD8232 analog front-end for real-time heart rate tracking, ECG waveform visualization, and wearable health prototypes. It is commonly used with Arduino and ESP32 boards that have analog input for logging and signal processing; unlike I2C, SPI, or UART sensor boards, this module is intended for analog ECG capture.
Pins
Pin names and layout can vary by module revision. Refer to the silkscreen labels on the board/module and the listing photos for the exact pinout and lead connections, and use the AD8232 datasheet for chip-level reference.

Frequently Asked Questions
How do I connect the AD8232 ECG module to an Arduino or ESP32?
Use the module with a microcontroller that has an analog input and follow the board silkscreen for the exact wiring on your revision. The included electrodes and lead cables make it easy to start ECG and pulse experiments.
Does the AD8232 ECG sensor use I2C, SPI, or UART?
This product is described as an AD8232 analog front-end for biopotential acquisition. It is typically read through an analog input rather than a digital bus such as I2C, SPI, or UART.
Can I use the AD8232 module with Raspberry Pi?
A Raspberry Pi does not have native analog input, so many builders add an external ADC or read the signal with an Arduino or ESP32 first. Plan your wiring and data path before building the project.
Where can I find the AD8232 pinout or datasheet?
Use the board silkscreen and listing photos for the exact module pinout, because module revisions can vary. For chip behavior and signal-conditioning details, consult the AD8232 datasheet.
