RAK2245 Pi Hat Change Frequency

Ordered a RAK2245 Pi Hat US 915 version, but the supplier sent the wrong version:

RAK 2245 Pi Hat 923MHz, SKU: 1013717743

Are there hardware differences between the two, or can I change the frequency to US 915Mhz through firmware and use the hardware in the USA? I would prefer not to do a RMA.

Thank You!

RAK2245 is a gateway product. The 915 and 923 are the same in hardware.

If you use the gateway firmware provided by RAK, you can refer to https://doc.rakwireless.com/rak2245-pi-hat-edition---lorawan----gateway-concentrator-module/configuring-the-gateway#set-up-rak-gateway-lora®-concentrator to change the frequency.
