I am interested in purchasing a RAK5146-125 mini PCIe card from your website. However, I noticed a discrepancy in the interface specifications between your site and the RAK website. While your website indicates that this card uses the SPI interface, the RAK website states that it supports the USB interface. Could you please provide clarification on this matter?

Hello Rony,

Welcome to the DigiKey tech forum community.

I looked at the data sheet on this part and it seems that it supports both SPI and USB.

RAK5146 WisLink LPWAN Concentrator Datasheet | RAKwireless Documentation Center

So yes it seems our product attributes need to be updated to include the USB interface option as well.
Sorry for the inconvenience this may have caused.


Hi rony.kuruvilla,

The “-125” version of the RAK5146 does not have an SPI interface. It does have USB, as seen from the table on page 12 of the datasheet. (Seems the link doesn’t open the pdf version. It can be found on the left side of their product page. The table below can also be found if one scrolls way down to the bottom of their product page.)
