The Espruino Puck.js v2.1 is a low energy Bluetooth smart button that can be programmed and debugged wirelessly with JavaScript.

New! Version 2.1 comes with more sensors, now comes with an accelerometer, gyroscope, FET, calibrated temperature sensor and improved Bluetooth signal strength!

It is both multi-functional and easy to use, with a custom circuit board, the latest Nordic chip, Bluetooth LE, NFC, magnetometer, temperature sensor, RGB LEDs, infrared and much more, all enclosed in a tiny silicone case. You get all the joy of an interpreted language, with some great sensors and wireless functionality!

Puck.js comes with the 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. You can start programming straight out of the box - no wires or software required!

The only difference between Puck.js v2 and v2.1 is the change of magnetometer from ST LIS3MDLTR to Memsic MMC5603NJ. All existing code will work unmodified as long as it isn't using Puck.magRd/magWr for register-level access to the magnetometer.

Note: Do not re-fit the PCB upside-down or force it into the case. If positioned correctly it should slide in. Forcing the PCB or fitting it upside-down could damage the aerial which will stop your Puck's Bluetooth from working correctly.

The Espruino family interacts well with NeoPixels. For more info, check out Espruino's page on the WS2811 and WS2812.

While the main advantage of the Espruino is its instant execution, it can also be used as a traditional board through a Web-based IDE hosted on your computer. The microcontroller also uses less power than Linux Boards (although its of course a lot less powerful as well) so will run longer on battery power. Simply take the Puck out of its packaging and get started! There's also much more info on the Espruino Puck.js page including tutorials, code examples, manuals, datasheets, and more!
