Perfect for wellness apps
HRV data seems consistent when compared to my chest strap. Great for building custom relaxation training tools.

Works well with my ESP32 project. The data stream is stable and the documentation helped me get started quickly.

Excellent documentation
SDK made integration easy. I was able to visualize the heart rate variability data within an hour of unboxing.

Decent module
Functions as described but I wish it had Bluetooth built-in instead of requiring a wired serial connection.
