I am using Arduino nano to drive multiple i2c devices, actually, they are premade modules which are available on eBay. ads1115 ADC, ds3231 RTC, 20x4 character LCD i2c module, at24c02 EEPROM module
all these modules have I2C SDA & SCL pull-up resistors in the module, please correct me if I am wrong.
doubt - if I connect these all devices to same SDA and SCl i2c bus what will happen to pullup resistances? according to the theory, since they are configured in parallel resistances will go low isn't it? means pull up resistance will go low?
how this will affect to my end device?
Is there a specified distance between SDA/SCL pins and pull up resistor?
