NINA-W102 Symbol Pins Aren't the Same as Provided by Manufacturer

[sparx777]

I'm trying to create my own board using the NINA-W102 module and the SAMD21G18A chip.
I am looking at the schematics provided by Arduino as a guide, but the pins don't match up.

Below is an image of the NINA symbol as provided by Arduino:

Below is the symbol provided by the manufacturer:

GitHub - u-blox/Altium-Designer-Library: Symbols and Footprints for Altium Designer

As you can see, there are many problems. Just to name a few:

1. Pin 1 on the Arduino schematic is SPIV_DI/GPIO23, but on the manufacturer symbol it is GPIO1/SPI_V_MOSI
2. Pin 5 on the Arduino schematic is LPO_IN/GPIO32, but on the manufacturer symbol it is GPIO_5
3. Pin 7 on the Arduino schematic is GPIO33, but on the manufacturer symbol it is LPO_IN

Not only this, but the manufacturer states that the 102 module has a built in antenna, but the Arduino schematic contains a U.FL connector.

At this time, when making my own schematic, I am just matching the pin numbers. I am ignoring the net/pin labels. So even though the pins don't have matching labels, I am still connecting the microcontroller to the matching pin number. However, due to the sheer number of differences, I am concerned that when I get this PCB built it's not going to work. Any advice?

Any advice?

You can use the interactive PCB viewer and see the traces on the PCB.

https://docs.arduino.cc/hardware/nano-33-iot

Go to Resources and scroll to the bottom of the page. Click "Open Viewer" and then use the PCB tab. You can search for signal names and get them highlighted. There are not too many pins, so should be a short exercise to give you some additional confidence.
