Frequently Asked Questions
How do I connect the MAX30102 module to Arduino, Raspberry Pi, or ESP32?
This module uses I2C, so wire it to your controller's I2C pins and follow the board silkscreen and your platform documentation. Check the exact pinout in the listing photos before powering the module.
Does the MAX30102 sensor measure both heart rate and SpO2?
Yes. The product description states that it measures pulse rate and SpO2 blood oxygen levels in one compact sensor module.
Is this MAX30102 board I2C, SPI, or UART?
The module is described as an I2C sensor board. If you are choosing code libraries, look for MAX30102 examples that support I2C rather than SPI or UART.
Where can I find the MAX30102 pinout and voltage details?
Use the board silkscreen, product listing photos, and the MAX30102 datasheet to confirm pin names and electrical requirements. Exact details may vary by module revision.
Are the pins pre-soldered on this module?
Yes. This version includes pre-soldered pins for easier hookup during prototyping and testing.
