Onion Omega2 - $5 WiFi Linux computer

The Onion Omega2 is a miniature Linux computer with integrated storage and WiFi connectivity. It runs on Linux so it supports many programming languages such as C++, Python, PHP, nodeJS etc, plus there are apps you can install for different purposes.



The base Omega2 model costs just US$ 5 and comes with a 580MHz CPU, 64MB RAM, 16MB storage, b/g/n WiFi, 15 GPIO ports, 2x PWM, 2xUART pins and I2C, SPI and I2S interfaces.


There is also an Omega2 Plus version that is currently US$ 9 and has 128MB RAM, 32MB onboard storage and an MicroSD slot, which might be more suitable for the complex projects.



Expanding it's connectivity is easy, there are 4 docks available for this little thing: the standard Expansion Dock (see image above) breaks out all the GPIO pins and adds USB support, the Mini Dock is aimed at volume-constrained applications and the Power Dock allows the Omega2 to run on a LiPo cell (and to recharge it). The one I love though is the Arduino Dock R2 - an Arduino Uno in which you plug the Omega2:



You can also use Expansions (tiny modules tht add certain functions like OLED display, Bluetooth or Ethernet connectivity, sensors etc) plugged in the Expansion Dock or Power Dock.

The reason I am writing this article though is that the Omega2 is a huge Kickstarter success. It reached it's funding goal in just 7 hours and now 4 days in is at almost 800% funding, with 30 more days to go. As we speak, it is ranked #2 most popular project on Kickstarter.

With all the mini computers / development boards out there at this moment makers have a lot to choose from, but this thing raises the bar so high that might very well turn into the next Arduino or RaspberryPi.
