Disable RTC | I2C-Address 0x68

Hello Community,

I am currently working on an projekt that required me to have one ADC, one DAC and some Digital Input and Outputs.

For this the Expander Pi looked like a great board to use, because it combines everything i needed. But I have a problem with the RTC that is installed on the Board. I need the I2C-Address of this RTC.
Is it possible to remove the RTC or disable the RTC?

Is there an easy way to disable it? For example with removing an resistor?

In advance thanks for the help.

To disable the RTC on the Expander Pi you will need to remove the DS1307 RTC chip. It is the 8-pin chip marked U4 next to the battery holder.

You should be able to unsolder the chip with a soldering iron by carefully heating the pins on each side of the chip in turn and applying a small amount of pressure under the chip with a small screwdriver or tweezers.
