Meet the Spark Core.
A tiny Wi-Fi development board that makes it easy to create internet-connected hardware. The Core is all you need to get started; power it over USB and in minutes you'll be controlling LEDs, switches and motors and collecting data from sensors over the internet!
No need to ever plug the Core into your computer; you can write code in our web IDE and download it wirelessly to the Core.
Familiar with Arduino? The Core uses Wiring, the same programming language that Arduino uses. Plus, with an accessory called the Shield Shield, you can connect the Core to any standard Arduino shield.
How do you connect a Wi-Fi device to your network when it doesn't have a screen or keyboard? With Smart Config, the Core's one step set-up process. Bring the Core online in seconds from any iOS or Android device.
