Puck.js – the ground-breaking bluetooth beacon

About this project

Puck.js is a low energy smart device which can be programmed wirelessly and comes pre-installed with JavaScript. It is both multi-functional and easy to use, with a custom circuit board, the latest Nordic chip, Bluetooth Smart, Infra-red and much more, all enclosed in a tiny silicone case.

We have an easy to use graphical editor, so it’s perfect for any maker, whether you’re just starting out or have been making for years. You can start programming straight out of the box – no wires or software required!

Why choose Puck.js?

Bluetooth Smart (or Bluetooth Low Energy) is an amazing technology – it’s now built into virtually all Phones and Computers, and Bluetooth Smart devices have a battery life of years.

Puck.js - the ground-breaking bluetooth beacon

Most manufacturers conveniently gloss over the difficulties of programming their hardware, and other beacons are provided without software or left crippled by their boring factory-installed software. Puck.js is different – it comes with our Open Source JavaScript interpreter Espruino pre-installed, which makes it incredibly easy to use and means you can get started in just seconds, without any prior programming experience.
