Get a unique PJON bus id

Contribute to the growth of the first global, decentralized, private network infrastructure. Fill in the form below to obtain a 4 bytes address to identify you and your devices.

Why get a bus id?

A bus id is used to provide identification when a PJON bus is directly connected or sharing its medium with others. To make sure that the bus id you use is unique, and not the same used by your neighbour, get a unique official bus id released here filling in the form below. The use of a bus id enables to control devices securely but also to communicate with other makers nearby. It is finally possible to setup a private, decentralized physical network infrastructure and anonymously connect to each other without an internet connection.

PJON - Avoid collision with a valid unique bus id

The bus id registration is optionally anonymous. Sharing the medium used and the location into the public domain may be useful if you are interested to connect your bus to other systems. The email address is kept private and it is used solely to inform you privately about updates, vulnerabilities or bugs. Requests for data deletion from our database can be sent to

if a wireless medium is selected a blue circle appears representing the communication range, use the handles to set its real extension.

Strategies abstraction

PJON uses strategies to physically transmit data, abstracting the data link from its procedure. A Strategy is a class containing the minimum required set of features to support transmision and reception of frames; many strategies are available to communicate data through various media and protocols. Take a look at the strategies video introduction for a brief showcase of their features.
