| 30 | HP0D has passed Helium Full Hotspot Approval. It supports the **miner feature from Helium** and has a built-in ATECC608 encryption chip. It can be used as a Helium Full Hotspot for the project. It also supports Semtech packet forwarder and LoRaWAN Station connection, it is fully compatible with LoRaWAN protocol.HP0D supports two LoRaWAN servers at the same time, **users can use HP0D for helium mining and connects max 2 x LoRaWAN servers at the same time**. | ||
