The Omega2+ is the upgraded version of the Omega2. It comes packed with built-in Wi-Fi, a MicroSD slot, and a powerful processor among other things.

The Operating system
The Omega2 runs the Linux Embedded Development Environment (LEDE) operating system, a distribution based on OpenWRT. This distribution gives the Omega2 access to the OPKG functionality, allowing you to download packages to enhance your experience.
The Omega LED
The Omega LED is a great tool for communicating information with a user. It notifies you when your Omega is on, when it’s off, and when it’s booting.
The Omega LED uses GPIO44, and can be programmed to do a number of cool things. You can learn more about the LED in the article on how to use the Omega’s LED
The Omega’s can be reset using GPIO38. When plugged into a Dock (e.g. Expansion Dock), this GPIO gives various functionality to the reset button found on docks. For example, a quick button press triggers the reboot command, whereas holding the button for about 10 seconds will trigger a factory reset command.
MicroSD Card Slot
The MircoSD card slot can be used to expand the Omega2+’s storage capacity to ridiculous levels. If 32MiB was a problem for you, you can now hit it with a tactical warhead. To help you get started, there’s a guide on using a MicroSD card.
The slot can be found at the bottom of the Omega2+. To physically mount a MicroSD card, slide it into the slot, push it down until it clicks. If it pops all the way back up, just do it again, and it should stay.
The WiFi Antenna
The on-board antenna is a ceramic surface-mount chip antenna. It’s small but packs a punch, the Omega’s WiFi signal is able to travel up to 100m (300ft) line-of-sight outdoors.
The U.FL Connector
Connect an external antenna to the Omega’s male surface-mounted U.FL connector. An external antenna can be used to extend the range of WiFi connectivity or provide a very directional signal. If a U.FL antenna is plugged in, it will be used as the default antenna, no setup required.
