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. In addition, you can control the Espruino from almost anything – Windows, Mac OS, Linux, RasPi, Android, anything that can talk to a USB Serial port.
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, it has loads of IO pins, and it can be used as an IO board for PCs, Macs, or Rasp Pis without having to program it first. Simply take the Espruino out of its packaging and get started!
- As of 12/18/2014 the Espruino board is now shipping with the following improvements:
- CE Approval
- 32kHz crystal on board (it's much better at keeping time accurately now)
- Pads for a Lithium Ion charger IC (if you want to fit one)
- Slightly moved, but much stronger Micro USB connector
- Much lower power voltage regulator – the old board drew 0.1mA in sleep, this one draws 0.03mA!
- Solder jumped so you can turn the reset button into a second general purpose button
