RAK13302 Device EUI

Does the RAK13302 1W Module for LoRa come with a LoRaWAN Device EUI?

With my RAK4631, the QR code is a Device EUI, but the RAK13302 only works with RAK3401.

The QR codes on my RAK3401 and RAK13302 have too many characters to be a Device EUI.

Do I need to buy a block of Device EUI to use the 1W LoRaWAN Module?

The RAK13302 does not come with a DevEUI.
You can create a unique DevEUI, AppEUI and AppKey in the LoRaWAN server when you setup the device.
