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.
