        Off-grid messaging using inexpensive hardware to create your personal
        mesh. Radios forward messages to the next to flood the network.
        Communicate kilometers/miles between nodes. Internet-connected relay
        nodes enable the conversation to move online too.

        Messages are AES256 encrypted. Only radios supplied with your channel
        settings (which includes the key) should be able to read your messages.
        Using multichannel settings you can send encrypted messages on one
        channel and still participate in a default Meshtastic mesh.

        a solar cell. Power management ensures the device will last the duration
