SEN0518 HearRate//The RED LED is not lighting up.
Daehyun.Kim 2024-08-06 02:40:30 148 Views2 Replies The LED is not lighting up. I am using a 3.3V power supply. I am using a development board rather than an Arduino board. The I2C communication is working correctly, but the red LED does not light up. Does the SEN0518 not operate with a single 3.3V power supply?
Will the modification of the hardware needed?
Or is there a specific code to turn on the light? rather than initiating codes

If you connect it to the Arduino, VCC should be connected to 5V. https://wiki.dfrobot.com/SKU_SEN0518_Gravity_MAX30102_Heart_Rate_and_Oximeter_Sensor

Thx for the reply.
In case of “max30102”, when you connect two pads at the backside, it works in a 3.3v.
Is there any way to do it on SEN0518?
