The Expansion Dock provides an easy way to power the Omega with any Micro USB cable and breaks out the Omega’s GPIO pins. You can use them to control external circuits or connect Expansion boards to extend the functionality of your Omega. It also comes with an on-board USB-to-serial chip that allows you to access the terminal directly from your computer.
The Mini Dock is designed to power your Omega for applications that do not require GPIO pins. Its small form factor makes it suitable to use for wireless applications such as Wi-Fi range extension, wireless printing, wireless video streaming, and more. The Mini Dock comes with a built-in USB port, allowing you to plug and play a variety of USB devices into your Omega. An on-board USB-to-Serial chip provides easy access the Omega’s terminal directly from your computer.
The Power Dock allows you to use any 3.7V LiPo battery to power your Omega and then charge the battery when it’s out of juice. It has the same form factor as the Expansion Dock and can also be used in the same way: no battery and receiving power through the Micro USB port. The Dock breaks out the Omega’s GPIO pins so you can use them to control external circuits or connect Expansion boards to extend the functionality of your Omega.
