The Intel® Edison is a compact computing platform that lets you integrate it into your projects. It's designed for "Internet of Things" projects and is very powerful for its small size.
The Edison has a bunch of features that make it appealing for all skill levels. It uses a 22 nm Intel SoC that includes a dual core, dual threaded Intel Atom CPU at 500 MHz and a 32-bit Intel Quark microcontroller which runs at 100 MHz. It's a lot of power for a board that's about the size of an LED Matrix.
The board supports 40 GPIOs and includes 1 GB LPDDR3, 4 GB EMMC, and dual-band WiFi and BTLE - which makes it essentially wireless.
Edison Dimensions: 35mm × 25mm × 4mm / 1.4" × 1.0" × 0.2"
