Good quality module
Solid build quality. Had to tweak the gain settings in code but got a readable waveform. Fast shipping.

Works as described
Sensitive to noise, so shielding is important. Otherwise, it performs well for the price point.

Great for learning bio-signals
Works perfectly with my Arduino Uno. Signal is clear when using proper electrodes. Note: This is for hobby use, not medical diagnosis.

Reliable sensor for prototypes
Used this for a university project. The lead-off detection is a nice feature. Clean output signal.

Excellent for education
We bought several for our workshop. Students found them easy to interface. Great documentation online.
Q: Is there a library available?
A: Yes, there are several open-source libraries available for Arduino and PlatformIO.
Q: Are electrodes included in the package?
A: Typically no, please check the package contents list. You will need standard 3-lead ECG electrodes.
Q: Is this module medical grade?
A: No, this is for educational and prototyping purposes only. Not for medical diagnosis.
Q: Does it output BPM directly?
A: No, it outputs analog signals. You need to process the data using a microcontroller to calculate BPM.
Q: Can I power this with 5V?
A: Yes, the module supports an operating voltage range of 3.3V to 5V.
