No, those should not be deleted. They are correctly indicated (in pale grey) as the alternate pin functions.I think there are some Pins to delete like TX/RX Pin 3/4 or DOUT/DIN Pin 7/8
Hi Nantonos,To clarify, they should not be deleted but they should be changed from DOUT to MOSI and from DIN to MISO.
I'm seeing an odd glitch on the "2" of I2C (and on Serial2, less obviously).

If you want to tackle the bottom board graphic document... As a noob I found it non-obvious in terms of the signal name labels referring to the inner solder pads, versus the board pins that are adacent to the labels.
I had forgotten that slave mode was an option.One small issue with calling the DOUT pin "MOSI" is it's still the output pin if you configure the SPI port in slave mode. The "SI" portion implies it would be an input.
Then again, almost everyone uses the SPI port in master mode.
