# Board support
|
||||
If you wish to add support for a specific board to the project, all you have to do (if it's ESP32 or nRF52), is write an additional entry for `Boards.h`.
|
||||
|
||||
This entry should include, at a minimum, the following:
|
||||
* whether the device has bluetooth / BLE
|
||||
* whether the device has a PMU
|
||||
* whether the device has an EEPROM (false in all cases for nRF52, true for ESP32)
|
||||
* pin mappings for SPI NSS, SCLK, MOSI, MISO, modem reset and dio0
|
||||
* the type of modem on the board (if undefined it defaults to SX127x)
|
||||
* whether the modem has a busy pin
|
||||
* RX and TX leds (preferably LEDs of different colours)
|
||||
|
||||
An example of a minimal entry can be seen below:
|
||||
`
|
||||
#elif BOARD_MODEL == BOARD_MY_WICKED_BOARD
|
||||
#define HAS_BLUETOOTH true
|
||||
#define HAS_PMU true
|
||||
#define HAS_EEPROM true
|
||||
#define EEPROM_SIZE 296 // minimum EEPROM size
|
||||
#define EEPROM_OFFSET EEPROM_SIZE-EEPROM_RESERVED
|
||||
const int pin_cs = 20;
|
||||
const int pin_reset = 19;
|
||||
// const int pin_cs = 1; not needed here
|
||||
// const int pin_sclk = 2; not needed here
|
||||
// const int pin_mosi = 3; not needed here
|
||||
// const int pin_miso = 4; not needed here
|
||||
const int pin_dio = 18;
|
||||
// const int pin_busy = 0; not present
|
||||
const int pin_led_rx = 5;
|
||||
const int pin_led_tx = 6;
|
||||
`
|
||||
|
||||
In some cases the SPI pins will not be required, as they will be the default pins for the SPI library supporting the board anyway, and therefore do not need overriding in the config.
|
||||
|
||||
If the SX1262 is being used the following should also be considered:
|
||||
* whether DIO2 should be used as the RF switch (DIO2_AS_RF_SWITCH)
|
||||
* whether an rf on/off switch also has to be operated (through the pin pin_rxen)
|
||||
* whether a TCXO is connected to the modem (HAS_TCXO)
|
||||
* the enable pin for the TCXO (if present)
|
||||
|
||||
An example of an entry using the SX1262 modem can be seen below:
|
||||
`
|
||||
#elif BOARD_MODEL == BOARD_MY_WICKED_BOARD
|
||||
#define HAS_BLUETOOTH true
|
||||
#define HAS_PMU true
|
||||
#define HAS_EEPROM true
|
||||
#define EEPROM_SIZE 296 // minimum EEPROM size
|
||||
#define EEPROM_OFFSET EEPROM_SIZE-EEPROM_RESERVED
|
||||
#define MODEM SX1262
|
||||
#define DIO2_AS_RF_SWITCH true
|
||||
#define HAS_TCXO true
|
||||
#define HAS_BUSY true
|
||||
const int pin_cs = 20;
|
||||
const int pin_reset = 19;
|
||||
const int pin_rxen = 10;
|
||||
// const int pin_cs = 1; not needed here
|
||||
// const int pin_sclk = 2; not needed here
|
||||
// const int pin_mosi = 3; not needed here
|
||||
// const int pin_miso = 4; not needed here
|
||||
const int pin_dio = 18;
|
||||
const int pin_busy = 7;
|
||||
const int pin_tcxo_enable = -1;
|
||||
const int pin_led_rx = 5;
|
||||
const int pin_led_tx = 6;
|
||||
`
|
||||
|
||||
If the SX1280 is being used, the following should also be added:
|
||||
* the TXEN and RXEN pins
|
||||
|
||||
An example of an entry using the SX1280 modem can be seen below:
|
||||
`
|
||||
#elif BOARD_MODEL == BOARD_MY_WICKED_BOARD
|
||||
#define HAS_BLUETOOTH true
|
||||

|
||||

|
||||
#define MODEM SX1280
|
||||
#define HAS_BUSY true
|
||||
#define HAS_RF_SWITCH_RX_TX true
|
||||
const int pin_cs = 20;
|
||||
const int pin_reset = 19;
|
||||
const int pin_rxen = 10;
|
||||
const int pin_txen = 11;
|
||||
// const int pin_cs = 1; not needed here
|
||||
// const int pin_sclk = 2; not needed here
|
||||
// const int pin_mosi = 3; not needed here
|
||||
// const int pin_miso = 4; not needed here
|
||||
const int pin_dio = 18;
|
||||
const int pin_busy = 7;
|
||||
const int pin_tcxo_enable = -1;
|
||||
const int pin_led_rx = 5;
|
||||
const int pin_led_tx = 6;
|
||||

# Feature request
|
||||
Feature requests are welcomed, given that those requesting it are happy to write it themselves, or a contributor considers it to be important enough to them to write it themselves. They must be written and **properly** tested before being proposed as a pull request for the project on [GitHub](https://github.com/liberatedsystems/RNode_Firmware_CE). **Manufacturers are encouraged to contribute support for their products back to this repository**, and such support will be receieved gladly, given it does not effect support for other products or boards.
|
||||
|
||||
# Caveat
|
||||
All contributions must not be written using **any** LLM (ChatGPT, etc.), please handwrite them **only**. Any PRs with proposed contributions which have been discovered to be written using an LLM will **NOT** be merged. The contributor concerned may rewrite their entire pull request **by hand** and it may be reconsidered for merging in the future.

# Frequently asked questions
|
||||
## Can I produce and sell my own RNodes using this project?
|
||||
Yes! Feel free to use the firmware in this repository for your produced RNodes. You do not have to pay a license to use this software commercially, as it is licensed under the GPLv3. If you fork it, you must understand your obligation to provide all future users of the system with the same rights that you have been provided by the GPLv3. Please also consider contributing additional features you design to this repository, to allow others to also use them.
|
||||
|
||||
It is also likely worth you reading [this material from Mark Qvist](https://unsigned.io/sell_rnodes.html). Do consider donating to him if your venture is successful, without him this project would simply be a schizo fever dream.

# RNode Firmware - Community Edition
|
||||
|
||||
This is the open firmware that powers RNode devices.
|
||||
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](https://github.com/markqvist/RNode_Firmware).
|
||||
|
||||
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](https://reticulum.network).

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](https://unsigned.io/rnode_bootstrap_console), which is hosted locally on every RNode, and can be activated and accesses at any time - no Internet required.

* Semtech SX1276
|
||||
* Semtech SX1278
|

## 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 **a couple of megabits per second**. Maximum output power will depend on the transceiver and PA setup used, but will generally lie between **17 dbm** and **27 dBm**.

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.
