Why did you make it?

I was amazed at how difficult it was to get started with (and then to debug) most Microcontrollers (especially ARMs), and the lack of support for different platforms. I thought that by putting the development tools on the device itself I could come up with a microcontroller board that could be programmed easily from almost any kind of computer.

Not only that, but your source code is on the board itself. If you make something with an Espruino board and need to change it a year later, your original code is still there waiting for you!

I love the product? it's the perfect solution for my project

I do li-ion powered G-scale locomotive with remoote control. The brains of the loc is Espruino. The choice of Espruino is explained by:
- javascript, as I'm non profi-programmer but I do know JS and NodeJS and all my other systems are based on NodeJS
- Wifi on board
- arduino-like, with lot's of supproted modules
- good support from the web-site
- asynchronic languge (JS), I suppose it's the best solution for running different tasks simultaneously

And with exception that I killed two boards due to inproper wiring the board itself is quite stable.

Good quality

Fast delivery, good quality, nice to have at least simple instruction in package. Trying different cases and lessons espruino web-site.

Useful board in compact format

The product itself is really nice, a compact format board, headers soldered already, perfect for breadboard use, but the documentation and the work around it Gordon has done is what makes it. There is no messing around with software & firmware updates are painless.

Perfect microcontroller for anyone who knows JS

Gordon has made something really amazing here.

Perfect for small projects, and even suitable for larger ones if you can think your way around some problems.

Great support from Gordon on the forums.

An amazing technology: Espruino

Espruino Wifi (and also Pico) is THE awesome technology for embedded devices. Once you have started to use it, you understand that you will achieve incredible connected objects. Great documentation and service. Fast shipping. The technology that helps me achieving many projects in short time. Thank you Gordon.
