How to determine which quectel ec200t I have?

I have Quectel EC200T-EU with a PCIe slot but throughout the Internet, I found 2 manuals one is EC200T PCIe and another EC200T PCIe-c and the pinout in these two manuals differ. so how to find if mine is with “C” or without it?

Hi @kaxa_gvimraze
There is a specific model number on the barcode sticker on the back of the module. If the standard PCIE does not have -C, it means it is an ordinary PCIE module. PCIE-C will be marked with -C. If you are not sure, you can take a picture of the module and show it to me.
