For other great embedded Javascript development boards from Espruino, check out the classic
Espruino and the little Espruino Pico.
The Espruino is a tiny computer with a JavaScript interpreter, allowing for instant feedback from
whatever device you're working with. Simply set up your code with the Espruino and send it to the device
without having to wait for the board to erase and reprogram the flash - it's fully interpretted!
The Espruino's fast response time has a lot of advantages. It allows for quick and easy debugging and is a
great way to test your project before your big reveal. This module is a miniature, embeddable version of
the Pixl.js - it just contains the Espruino-running Bluetooth LE module, regulator and reset button. In
addition, you can control the Espruino from almost anything that has Bluetooth Low Energy.
Each order 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 using WebBluetooth for an IDE!
Some light soldering is required to power this small breakout. It isn't the easiest Espruino to start with,
but when you need to go small this one is as tiny as it gets.
