Re: Best Way to Interface ADS1115 (4V) with ESP32 (3.3V) via I²C?
Yes, I was thinking about that and connecting the pull-up resistors to 3.3V to ensure compatibility with the ESP32 However I have another concern my sensors operate between 3.6V and 6.4V and it is recommended to power them with 4V or above meanwhile the ADS1115 is powered by 3.3V from the ESP32 ...

Best Way to Interface ADS1115 (4V) with ESP32 (3.3V) via I²C?
Hi
I have a set of sensors operating between 4V - 6V, and I am using an ADS1115 16-Bit ADC to connect them to an ESP32. I have powered both the sensors and ADS1115 with 4V, and I have also powered the ESP32 through the VIN or 5V pin using 4V.
This means that SDA and SCL will transmit data from ...
