Spark Core: WiFi for Everything

The Spark Core is an Arduino-compatible, Wi-Fi enabled, cloud-powered development platform that makes creating internet-connected hardware a breeze.

Connect to the internet in seconds. Access it from anywhere with no setup. Reprogram your Core wirelessly from our web IDE or through the command line. Use Wiring code, the same language and libraries that you know and love from Arduino. Everything about the Spark Core is designed to make your life easier.

The Spark Core is open source hardware, designed to be easy to extend, improve, and incorporate into your own products and projects. We use open standards like TLS/SSL and Protocol Buffers for communication, and readily available components for our hardware. Our REST API makes it easy to extend your Core and pair it with other online services.
