Receiving Different Voltage Values from ADS1115

Hey there,

A couple of days ago, I have noticed that the SDA and SCL inputs output higher than 3.3V which is not advised to configure the setup for raspberry pi. After various tryouts, SDA and SCL pins started outputting different voltage values, 3.3V and 2.7V, respectively. Moreover, the ADS1115 is not recognized by the raspberry pi i2c but receiving healthy results from SHT31D.

Is it normal to have such a difference? Thanks in advance!

Strange. I’ve never measured SDA or SCL, so I’m not sure if that’s typical. My gut says there’s an issue with your Pi. Do you have any other Pis you can also measure?

Ordered a new one yesterday. Going to check this asap.
