Open source Bluetooth low energy beacon simple to program and debug
Subs & Systems
The intentionally hacker-friendly Puck.js is open source, supports both the iBeacon and Eddystone beacon formats, and will be supplied with firmware updates for the forthcoming Bluetooth v5.0 specification that will quadruple the range and double the speed of Bluetooth v4.2. Puck.js has a circular 35mm diameter form-factor that is 10mm thick, with a silicone rubber cover and plastic base. It is powered from a CR2032 coin cell battery and includes a magnetometer (digital compass), user-assignable tactile button, and four (Red, Green, Blue, and Infrared) LEDs.
Williams says Puck.js is like a development kit that's also a finished product. "You insert a battery, put the case on, and it's a ready-to-go Bluetooth low energy beacon straight-out-the-box with no wires of software required," he adds. "At the same time it's very easy to add new functions and features for home automation projects, IoT prototyping, or education purposes."
