Espruino is a small computer that anyone can use to control things around them. Its JavaScript interpreter gives you instant feedback so that you can experiment and develop whatever your level of experience. Even if you've never written code before、you can still use the graphical code editor to write programs without typing a single word！
Features：Works on Windows、Linux、MacOS and Android（via Bluetooth or USB OTG）
Less than half the size of a business card just 54mm×41mm
Using the popular JavaScript language、Espruino supports Strings、Maps、Objects、and Dynamic Arrays right out of the box！
72Mhz ARM microcontroller with 256KB of Flash memory and 48KB of RAM
Micro USB connector、Micro SD card connector、and a JST Battery connector with a wide input voltage range of 3.6v to 15v
