特徴

• Espruino Pico is a tiny microcontroller board that runs JavaScript（it doesn't need to be plugged into a computer）、making it easier than ever to control electronics in the real world. 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 have uploaded code、you can inspect and change variables（including functions）while your program is running. If you make something with an Espruino Pico and need to change it a year later、your original code is still there waiting for you！
• This is unpinned version、if you want pre-soldered pins、please visit Espruino Pico（pinned）.
