PJON – Communications bus system for Arduino

In plain words

PJON is an open-source communications system designed for Arduino microcontrollers and embedded devices. It enables multiple devices to exchange data over a shared bus, supporting various physical layers including serial, wireless, and ethernet connections. The system is intended for makers and developers building networked Arduino projects that require reliable inter-device communication. PJON provides a flexible alternative to traditional point-to-point connections when coordinating multiple microcontrollers.
