Please be aware of the difference between the RAK4631 (Arduino bootloader) and the RAK4631-R (RUI3 bootloader). Meshtastic requires the Arduino bootloader. If you have a RAK4631-R, please see the [instructions for converting the bootloader](/docs/getting-started/flashing-firmware/nrf52/convert-rak4631r).
Further information on the RAK4631 can be found on the [RAK Documentation Center](https://docs.rakwireless.com/Product-Categories/WisBlock/RAK4631/Overview/#product-description).
The RAK11200 does not contain a LoRa transceiver, and thus needs to be added separately in the form of the [RAK13300 LPWAN module](https://store.rakwireless.com/products/rak13300-wisblock-lpwan). This occupies the IO Port of the base board.
Further information on the RAK11200 can be found on the [RAK Documentation Center](https://docs.rakwireless.com/Product-Categories/WisBlock/RAK11200/Overview/#product-description).
