I bought two RAK2245 with 915MHz by mistake.
I found that the RAK2245 have a resistor labeled 915MHz on the PCB and also other resistor footprints for the other lora frequencies.
Is it possible to change to 868MHz by just replacing the little resistor to the label 868MHz?
I think you need a new RAK2245 with 868MHz.
