I have two modules that uses I2C and both connected to an Arduino. one of them have two 10K pullup resistors.
The other one is an 16X2 LCD I2C:
I couldn't find an schematic for this module but tracked the connection with DMM.
Connecting the LCD I2C modules causes the first module (ADC) readings get way off.
Those two 4.7K are pullup resistors? if yes can I safely remove them because I have pullups on the ADC module?
