The Omega2 Expansion dock is a powerful piece of hardware that simplifies the usage of your Omega. It allows you to power the Omega and communicate with it via serial through the Micro-USB port, and makes it incredibly easy to use the GPIOs and Onion Expansions.

The Expansion Dock has a 30 pin Expansion Header, allowing you to use all of your Onion Expansions. The Expansion Dock is powered by the Micro-USB port that supplies 5V to the Dock. This voltage is stepped down to the required 3.3V required to power the Omega, and also provides 5V to the Expansions and USB Host port.

There is a great RGB LED that you can control through the command-line interface and easy communication via the USB-to-Serial chip located in the center of the board. The reset button, located between the power switch and the Micro USB port, can be used to quickly reboot your Omega, or you can hold it down for a factory reset if your Omega is ever in a bad state.

The Expansion Header is a convenient tool that gives you easy access to the Omega's GPIOs, and allows you to connect Onion Expansions directly. The Expansion Header is labelled to show you what GPIO is connected to each section.

Board Features:


  • Micro-USB port - USB-to-Serial connection between the Omega and a computer
  • Power Switch - cut power to the Omega, but not the serial chip
  • Reset button - Reboot and factory restore
  • Omega USB Port - USB 2.0, and is a type A connector
