Discover the PJON Open Standard

With PJON makers can communicate with each other and with devices securely, anonimously 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. You can build a network infrastructure in minutes and connect devices with no need of a cloud service or a centralized platform you don't fully control.

Know more about the PJON protocol

PJON is an arduino-compatible, open-source, multi-master, multi-media network protocol that can be easily cross-compiled on many MCUs and systems like ATtiny, ATmega, SAMD, ESP8266, ESP32, STM32, Teensy, Raspberry Pi, Linux, Windows x86, Apple and Android. PJON can be applied in low-data-rate applications as an alternative to proprietary protocols like 1-Wire, i2c or CAN but can also be applied in place of IP to interconnect more complex networks.

Review and comments from users

I vividly remember how everyone was stunned by letting arduinos communicate passing through the human body (holding the leads with hands), it is incredibly resilient, if user does’t mind the speed.

I really like your PJON library. Actually I consider it miracle, specially your one-wire bus implementation. I'll keep you posted with some minor improvement proposals if you don't mind :-)

Thank you very much for the awesome book. It is better than I expected. Clear layout and detailed information about each layer and hook up guide, examples etc. I really love the ASCII arts in the book.
