The Electric Imp
This little platform comes in a package that looks like an SD card; however, it is not an SD card and is not SD-card-compatible.
Housed inside the case is an 802.11b/g/n WiFi module and a strong antenna. Additionally, it includes an A Cortex-M3 processor, which allows connections through six I/O pins. Although there are only six, they can be used for the SPI, UART, and I2C protocols, or they can be used as analog/digital input and output, or pulse-width modulation.
The Imp is meant to provide users with a secure way to communicate over the Internet. All the code developed for the Imp is written in a browser-based IDE, which will then run on the Imp. The code is written in "Squirrel," a C-style, higher-level language. Due to its SD card geometry, many breakout boards and shields are available to help users get started with the Imp.
In addition, there are also blogs, a Wiki, tutorials, and help sites available for projects and development. This is a great, low-cost product for users looking for a modest connectivity option with available support.
