### RAK4631

:::info
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/guides/convert-rak4631r).

### RAK11200 / RAK13300

:::caution Note
Only supported on the RAK5005-O base board.
:::

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.
