What are those 3 slots on the top left? Looks like 3 slots for sim cards, but there's no mention of SIM support and only 3 quantities of something are antennas.
That picture doesn't represent the actual hardware. Pretty confusing, but at least they acknowledge it in its description:

That looks like it's the Banana Pi BPI-R4 WiFi 7 router board: https://www.cnx-software.com/2023/11/23/banana-pi-bpi-r4-wif.... And yeah, those are three nano SIM card slots. You can see the image of the underside with a bunch of places to attach the relevant antennas.
The article needed a picture, so I guess they decided to use a picture of a completely different device.
