Is S1300 running on 512MB or 256MB ram?

It says 512MB here: GL-S1300 / Convexa-S - GL.iNet

and 256MB here: https://www.amazon.de/-/en/GL-iNet-GL-S1300-Gigabit-Pre-Installed-Networking/dp/B07XYZPQW4

It’s 512MB ram, like here:

Seems like the official store for Amazon DE has copy pasted the B1300 info incorrectly.

The Q&A also says it doesn’t have BLE. Very confusing.

Is there a convexa with 512MB without BLE/Zigbee but that supports USB Zigbee?

Prefer to use Zigbee USB with UI and confirmed device support
