Solid hobbyist tool
Works well for visualizing heart signals on an oscilloscope or serial plotter. Be aware that there is no galvanic isolation, so always power this with a battery when testing on humans for safety.

Excellent for educational projects
I used this module for a university biomedical engineering project. The signal clarity is impressive for the price point. Easy to interface with Arduino using standard analog reads. Just remember this is for learning, not medical diagnosis.

Easy Arduino integration
Plug and play with most existing libraries. The documentation provided by the community is helpful. Voltage range is flexible which makes it great for 3.3V logic boards like the ESP32.

Compact and reliable
Small footprint fits well into wearable prototypes. The snap leads connect securely. I appreciate that it runs on low power, making it suitable for battery-operated builds.

Good value but needs filtering
The hardware works as described. I noticed some 50Hz noise in my setup, but adding a software filter cleaned it up nicely. The lead-off detection is a handy feature to have built-in.
Q: Can this module be powered directly from a 5V Arduino pin?
A: Yes, the module supports an operating voltage range of 3.3V to 5V, so it is compatible with 5V logic boards.
Q: Does this module provide electrical isolation for patient safety?
A: No, this module does not have built-in galvanic isolation. For safety, we strongly recommend powering your microcontroller and module with a battery during human testing.
Q: What type of electrodes do the snap leads connect to?
A: The included snap leads are compatible with standard 3.5mm snap electrodes commonly used in ECG applications.
Q: Is this device certified for clinical medical use?
A: No, this product is designed for educational, hobbyist, and prototyping purposes only. It is not certified for medical diagnosis or treatment.
Q: Are there any libraries available for STM32?
A: Yes, several open-source libraries are available on GitHub that support STM32 platforms. Please check the product wiki for links.
