Reticulum implements a range of generalised interface types that covers most of
the communications hardware that Reticulum can run over. If your hardware is
not supported, it's relatively simple to implement an interface class. I will
gratefully accept pull requests for custom interfaces if they are generally

not supported, it's [simple to implement a custom interface module](https://markqvist.github.io/Reticulum/manual/interfaces.html#custom-interfaces).
Currently, the following interfaces are supported:
Pull requests for custom interfaces are gratefully accepted, provided they are
generally useful and well-tested in real-world usage.
Currently, the following built-in interfaces are supported:
- Any Ethernet device
- LoRa using [RNode](https://unsigned.io/rnode/)
