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 our 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!
