We can get 100 units into Australia from Pimoroni. If you order today, we can dispatch this stock between Dec 30, 2024 - Jan 06, 2025.
The Espruino WiFi is a tiny WiFi-enabled board that runs JavaScript code (it doesn't need to be plugged into a computer). You can program it with nothing but a serial terminal program, but there's also an IDE that runs in the Chrome Web browser.
It's got a syntax highlighted editor as well as a graphical programming language.
Once you've uploaded code, you can inspect and change variables (including functions!) while your program is running.
There's loads of documentation, tutorials and support for a huge range of different hardware too.
See how to get started here, or if you have any questions ask away on the forums!
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!
