RNode Firmware - Community Edition
This is the community maintained fork of the open firmware which powers RNode devices. It has been created to continue to expand development and support for more hardware devices, as the upstream repository is no longer accepting PRs for new hardware support. The original repository by Mark Qvist can be found here.
An RNode is an open, free and unrestricted digital radio transceiver. It enables anyone to send and receive any kind of data over both short and very long distances. RNodes can be used with many different kinds of programs and systems, but they are especially well suited for use with Reticulum.
RNode is not a product, and not any one specific device in particular. It is a system that is easy to replicate across space and time, that produces highly functional communications tools, which respects user autonomy and empowers individuals and communities to protect their sovereignty, privacy and ability to communicate and exchange data and ideas freely.
An RNode made from readily available and cheap parts, in a durable 3D printed caseThe RNode system is primarily software, which transforms different kinds of available hardware devices into functional, physical RNodes, which can then be used to solve a wide range of communications tasks. Such RNodes can be modified and built to suit the specific time, locale and environment they need to exist in.
Latest Release
The latest release, installable through rnodeconf, is version 1.72. This release brings the following changes:
- Added support for flashing T3S3 boards
- Added deep sleep support on T3S3
- Various quality updates for nRF / RAK4631
- Fixed a bug with antenna switch utilisation on RAK4631
- Updated console image to include latest packages
You must have at least version 2.1.3 of rnodeconf installed to update the RNode Firmware to version 1.72. Get it by updating the rns package to at least version 0.6.4.

It's easy to create your own RNodes from one of the supported development boards and devices. If a device or board you want to use is not yet supported, you are welcome to join the effort and help create a board definition and pin mapping for it!
Supported Transceiver Modules
The RNode Firmware supports all transceiver modules based on the following chips:
- Semtech SX1262
- Semtech SX1276
- Semtech SX1278
- Semtech SX1280
These also must have an SPI interface and DIO_0 pin connected to the MCU directly.
One Tool, Many Uses
The RNode design is meant to flexible and hackable. At it's core, it is a low-power, but extremely long-range digital radio transceiver. Coupled with Reticulum, it provides encrypted and secure communications.
Depending on configuration, it can be used for local networking purposes, or to send data over very long distances. Once you have an RNode, there is a wide variety of possible uses:
- As a network adapter for Reticulum
- Messaging using Sideband
- Information sharing and communication using Nomad Network
- LoRa-based KISS-compatible amateur radio TNC
- LoRa development platform
- Packet sniffer for LoRa networks
- Long range Ethernet and IP network interface on Linux
- As a general-purpose long-range data radio
Types & Performance
RNodes can be made in many different configurations, and can use many different radio bands, but they will generally operate in the 433 MHz, 868 MHz, 915 MHZ and 2.4 GHz bands. They will usually offer configurable on-air data speeds between just a few hundred bits per second, up to hundreds of kilobits per second. Maximum output power will depend on the transceiver and PA setup used, but will generally lie between 17 dbm (50mW) and 27 dBm (500mW).
The RNode system has been designed to allow reliable systems for basic human communications, over very wide areas, while using very little power, being cheap to build, free to operate, and near impossible to censor.
While speeds are lower than WiFi, typical communication ranges are many times higher. Several kilometers can be acheived with usable bitrates, even in urban areas, and over 100 kilometers can be achieved in line-of-sight conditions.
A Self-Replicating System
If you notice the presence of a circularity in the naming of the system as a whole, and the physical devices, it is no coincidence. Every RNode contains the seeds necessary to reproduce the system, the RNode Bootstrap Console, which is hosted locally on every RNode, and can be activated and accesses at any time - no Internet required.
The designs, guides and software stored within allows users to create more RNodes, and even to bootstrap entire communications networks, completely independently of existing infrastructure, or in situations where infrastructure has become unreliable or is broken.
Where there is no Internet, RNodes will still communicateThe production of one particular RNode device is not an end, but the potential starting point of a new branch of devices on the tree of the RNode system as a whole.
This tree fits into the larger biome of Free & Open Communications Systems, which I hope that you - by using communications tools like RNode - will help grow and prosper.
Getting Started Fast
You can download and flash the firmware to all the supported boards using rnodeconf. All firmware releases are handled and installed directly through the rnodeconf utility, which is included in the rns package. It can be installed via pip:
# Install rnodeconf via rns package
pip install rns --upgrade
# Install the firmware on a board with the install guide
rnodeconf --autoinstall
For more detailed instruction and in-depth guides, you can have a look at some of these resources:
- Create a basic RNode from readily available development boards
- Follow a complete build recipe for making a handheld RNode, like the one pictured above
- Learn the basics on how to create and build your own RNode designs from scratch
- Once you've got the hang of it, start building RNodes for your community, or even for selling them
Support development
Contributing
You can contribute features and board support to the project if you wish. Please see here.
Hardware donations
If you would like to see support added for a board which you possess, you may donate it to myself, Jacob Eva, so that I can implement support for it into this project. There will be no official timescale given for implementation however, but I will try my best when I have time :) Please contact me (scroll to the bottom) if you wish to donate hardware to the project.
Purchasing products
You can support the development of the RNode Firmware CE project by purchasing RNodes (to come in the future) and other products from Liberated Embedded systems, my online business. For more information on my business, please see here.
From time to time the creator of the Reticulum project, Mark Qvist, produces his own RNodes and sells them through his shop. You may support the development of open, free and private communications systems through purchasing these from him.
Monetary donations
I, the maintainer of this fork, am currently not accepting monetary donations. These are instead better directed to Mark Qvist, who created the original repository this one is based on, and is the core developer of the Reticulum project, which is what the RNode Firmware was designed to supplement as a network adapter. You can help support the continued development of open, free and private communications systems by donating to him via one of the following channels:
