Build the network of the future
With PJON® you can connect open-hardware and consumer-electronics products securely, with incomparable flexibility and with no need of a network provider or cloud service.
Embedded systems connected
PJON® (Padded Jittering Operative Network) is an open-source network protocol able to connect devices using most physical layers and media, such as wires (PJDL, Ethernet, Serial and RS485), radio (ASK, FSK, OOK, LoRa or WiFi) and light pulses (PJDLS). It is released in a single portable implementation that can be easily cross-compiled on many systems like ATtiny, ATmega, ESP8266, Teensy, Raspberry Pi, Windows X86, Apple and Android. It is a valid tool to quickly build a network of devices.GET PJON

The internet infrastructure is vulnerable, used as a tool of mass surveilance, propaganda and cultural subversion; looking at history and society today, it seems internet users will be soon aware, all at once, of its downsides. Day by day, internet revolutionary features have been eroded with the centralization of:
Information with search engines and cloud services
Functionality with proprietary applications and platforms
Connectivity with social media and providers
We are not only living days where fridges can be hacked, but also where the interruption of a cloud service can render many things useless and many people powerless, or where a single point of failure in the network can disconnect entire regions.
Thanks to the flexibility of the PJON protocol you can create local or decentralized networks in minutes using both open-hardware and off-the-shelf consumer-electronics products. PJON has a wide hardware support and it is able to operate on most existing protocols and physical layers:
With PJON® makers can communicate with each other and with their devices securely, anonymously and for free. This is possible thanks to the flexibility of the PJON protocol, able to operate on a wide range of media, such as wires, unlicensed radio frequencies or light pulses. Users are free to build a multi-media network infrastructure in minutes, handle data locally, operate devices in their private space and network with neighbours without needing paid connectivity or a cloud service.DOCUMENTATION
The PJON protocol handbook
This is the second publication about PJON, which contains the documentation, the specification, many application examples and troubleshooting techniques. The book is Made in Italy and within its 204 pages the whole PJON network protocol stack and its strategies are accurately described with graphs, color pictures and comments on its implementation. Choosing this handy format, you will always have PJON with you, also when not being connected to Internet.
