The Mini Dock provides power to the Omega2, and it allows you to plug in USB devices. It is designed primarily for volume-constrained applications, as well as applications that do not require any Expansions (networking, for example). The Mini Dock has a USB-to-serial chip just like the Expansion Dock.
At about the same size as the Omega, the Mini Dock is meant for projects where space is limited and the Omega’s GPIOs aren’t needed. It’s ideal for USB-based or wireless networking projects!
You can provide power to the Omega and Dock with any Micro USB cable. The Dock includes a regulator circuit that ensures the Omega always receives the stable 3.3V it needs to operate optimally.
The Dock exposes some key Omega features to the user:
Connect USB devices directly to your Omega
Press the Reset Button to reboot your Omega, hold it for 10 seconds to perform a factory restore
Turn your Omega on and off with the Power Switch
Ease of Use
Thanks to the on-board USB-to-Serial chip, you will always have access to the Omega’s serial terminal. No network connectivity required, just a solid USB connection. The serial terminal is especially handy when accessing the bootloader to reflash your Omega.
