Custom Board configuration

3. You can keep them as in the PCA10056 board file

4. Sorry, this was entirely my fault, I glanced a bit too quick on the board file. Forget my previous point, just make sure that the I2C pins are assigned to the left or under side of the chip as the pins on the right side and upper side of the IC are marked as low frequency/low drive in the product specification.

5. This is usually done as part of the pre-processor defines. I've included a snippet from SES, if you use GCC then it's done in the bottom of the makefile.

3. The RX Pins for the different definitions is different, should I keep this exactly like it was?

4. I don't see any SWD pin assignment in the PCA10056 header file. Also, the signals I mentioned in OP are custom signal connected to corresponding pins, I wanted to know if they were configured properly.

5. Right, I am confused where I have to define this and take out PCA10056 being defined since I am using the example from the SDK to make the project?

Hi.

If you're using nRF52840 then PCA10056 would be the better option to base your custom board file on.

Just an "alias" for LED1 and LED 4, not necessary.
Depends on your project. If you're going to use an example from the SDK that uses the buttons then yes it's necessary. If not, then no.
Used internally in some of the serialization files.
The SWD pins on the nRF52 are not optional. It has dedicated pins for this. Use the same as in the PCA10056 board file.
Correct. You only need to define custom_board.
