USB2.0, UART, I2C, SPI, 12 GPIOs, all available on the Expansion Header
Linux Operating System with support for many programming languages
Support for plug and play Onion Omega Expansions and USB devices
Excellent starter pack for making projects with the Omega
The Omega2+ IoT computer is Onion's 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. The Expansion Dock is the perfect companion for the Omega, making it incredibly convenient and easy to use as well as exposing a variety of the Omega's features. It breaks out the Omega's GPIOs on the Expansion Header, providing support for plug and play Onion Omega Expansions or for using the GPIOs to control external circuits. Connect USB devices directly to the Omega with the built-in USB Type-A connector. The on-board USB-to-Serial chip provides easy access the Omega's terminal directly from your computer. At the Omega2+'s core is the MT7688 SoC that features a 580 MHz MIPS CPU, supports 2.4 GHz 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 on-board flash storage, double that 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 USB2.0 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.
