Good hobby sensor
Data looks consistent though needs filtering. Not for medical use but great for learning embedded systems.

Great for STM32 projects
Works perfectly with my STM32 board. I2C communication was easy to set up using standard libraries.

Requires calibration
Good module but you need to tune the LED intensity for best results depending on skin tone.

Fast shipping and works
Tested with Arduino Uno. Reads heart rate reliably during rest conditions.
Q: Does it work with 5V logic microcontrollers?
A: Yes, the breakout module includes a voltage regulator and level shifting for 5V compatibility.
Q: Is this device medical grade certified?
A: No, this module is intended for hobby, educational, and development use only. It is not certified for medical diagnosis.
Q: Can it measure SpO2 accurately without calibration?
A: It provides raw data for estimation. Algorithm calibration is required for accurate SpO2 readings.
Q: What is the default I2C address?
A: The default I2C address is typically 0x57, but please refer to the specific datasheet for confirmation.
Q: Are there ready-made libraries available?
A: Yes, multiple open-source libraries exist for Arduino, STM32, and ESP32 platforms.
