A Bluetooth microcontroller with built-in LCD display and Arduino footprint

Pixl.js is a smart LCD with Bluetooth LE. Monitor and control other Bluetooth LE devices. Pixl.js can act as a wireless display, or a smart conference badge, or even display the status of your code - all while drawing tiny amounts of power. Pixl.js uses Espruino, so you program it in JavaScript: you can modify code without rebooting, and even debug - completely wirelessly.

Pixl.js's unique design allows you to plug in a huge array of existing Arduino shields while still using the LCD and buttons, including: Ethernet, WiFi, Motor drivers, even GSM, with no soldering required!
