Rak supports SX1280

Where can i find out if rak7268 supports sx1280 lora devices?

RAK7268 does not support SX1280.
We have LoRa concentrator for 2.4GHz LoRa, but it works only with with the RAK7391 WisGate Connect

so since sx1280 operates at a frequency of 2.4GHz it is not supported by rak7268?

The RAK7268 is not available with the 2.4GHz concentrator and the firmware does not support it.

You can buy the 2.4GHz concentrator RAK5148 separate and build a gateway based on RPi.

RAK7391 is the easier way IMHO

Hi may I ask if rak7268 supports SX1276/SX1278?

Depending on the version you buy RAK7268 supports any LoRaWAN node that works in [EU868, IN865, RU8964] or [US915, AU915, KR920, AS923-1/2/3/4]

Because the RAK7268 has only one concentrator and the concentrator is either for 8xxMHz or 9xxMHz.

I am not sure if I understand your reply, this is the specs, are these details is it helpful in determining which frequency band it is operating in?
the concentrator is 2287

it also has another space for another sx, is it possible for me to buy the rak5148 and add it to the rak7268

(1) Frequency Range
In the gateway web UI, go to Configuration and check what regions are shown in the Frequency Plan
If you see EU868/IN865/RU864 you have a gateway with a 8xx MHz concentrator. If you see US915/AU915/… you have a gateway with a 9xx MHz concentrator.

(2) Use second slot
No, it does not work, because the firmware of the RAK7268V2 does not support the 2.4GHz concentrator.
