World’s smallest Linux server, with Wi-Fi built-in.
The Onion Omega2 is the latest simple and affordable development board, which combines the tiny form factor and power efficiency of the Arduino with the power and flexibilities of the Raspberry Pi.
Starting at just $5, the Omega2 is less than 1/4 the size of the Raspberry Pi, and less than 1/3 the size of the Arduino Uno. The tiny computer has integrated Wi-Fi and onboard flash storage. This means you don’t have to worry about buying Wi-Fi dongles or installing operating system images onto external SD cards.
The Omega2 features 580 MHz CPU, 64MB of memory, and 16MB of storage. For the same price, its main competitor, the Raspberry Pi Zero has a 1 GHz CPU, and 512MB of RAM. Although the Pi Zero does have the Omega2 beat in performance, the Omega2 has built-in Wi-Fi, something the Pi needs a special add-on for. Also, the Omega2 has a cloud-based feature called Onion Cloud that allows you to control the board via the web browser on any computer, anywhere in the world, and regulate hardware-software interactions with many cool APIs.
“Omega2 is a Linux computer designed for hardware projects. It does a few things. First, it allows software developers to develop hardware using high-level programming languages and familiar developer tools. It also allows non-technical people to program using drag and drop interface,” said co-founder Boken Lin. “We created modular expansions so people with limited electronics knowledge can still build complex hardware projects.”
The Onion Omega2 is available for preorder on Kickstarter until August 23rd. The price starts at $5, with the final product shipping in November. There are options to purchase docks that give the Omega2 some expansion slots to work with accessories, such as for power and storage. Also, for extra $4 you can choose the Omega2 Plus, to get double the memory and storage, and on top of that – a built-in microSD slot.
