The Omega2+ IoT computer is Onion’s top-end Linux-based WiFi development board designed to enable makers of all skill levels to build connected hardware applications. Plug in your Omega, and it will boot the operating system right away, allowing you to develop in your favorite programming language, create web applications and interface with a variety of hardware with minimal time and effort spent getting started.
At the core of the Omega2+ is the MT7688 SoC, which features a 580MHz MIPS CPU, supports 2.4GHz IEEE 802.11 b/g/n WiFi as well as 10M/100M wired Ethernet network connectivity, and operates at 3.3V. The Omega2+ comes with 128MB of DDR2 DRAM memory and 32MB of onboard flash storage — double that of the Omega2! The storage space is expandable using the microSD card slot on the underside of the Omega2+.
The Omega was built to interact with other hardware, so it has a wide variety of hardware interfaces. It has dedicated pins for USB 2.0 and Ethernet as well as 12 GPIO pins that can be controlled by the user. These GPIOs can support the I2C, UART and SPI serial communication protocols.
The Onion Omega boards we carry are separated into three different categories: Mainboard, Dock and Expansion Board. This board falls into the Mainboard category, which means it is highly encouraged that you pick up a Dock since the Onion Omega utilizes a 2mm header instead of a standard 0.1".

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

Bought my first one of these little computers here. Works great. With the expansion dock I expanded its memory to 32 GB using a micro SD card. Adding a USB webcam to that, and I’ve got a WIFI webcam with 32 GB storage.
I build a Christmas light controller IoT broker with this little gem! Following the instructions on this page (makoserver.net/apps/LightController/ and makoserver.net/download/7688/) to set up the broker and couple of Sonoff 4ch relay controllers (Sparkfun should carry these nifty devices!).
