An Introduction to a New Low-Cost Internet of Things Computer.

The Omega2 is an single-board computer (SBC) geared for the Internet of Things (IoT) market, billed as the “world’s smallest Linux server.” It runs a variant of Linux known as OpenWRT, which is most commonly found on embedded devices like routers. It’s low power and really tiny; at 43mm×26mm×10mm, it’s just a little larger than an Arduino Pro Mini.

Don’t let that fool you into thinking it’s not a real computer, however. It’s surprisingly powerful for the size, with its MIPS processor running at 580MHz. It supports up to 256MB of RAM, and it can support SD card storage. It supports 802.11b/g/n 2.4GHz WiFi and 10/100M Ethernet, as well as a multitude of other protocols like UART, I2S, I2C, and SPI. It operates at 3.3V, but its docks and expansion boards come with a convenient onboard voltage regulator, which means you can power it with a variety of power supplies without having to worry about blowing it up.
