Announcing the Power Dock 2

We’re very proud to announce the latest addition to the Omega2 family, the Power Dock 2!

The Power Dock 2 is the new and improved version of our original Power Dock. Just like the original, it can power your Omega and peripherals with any 3.7V LiPo battery, allowing you to take your Omega project on the go!

The main addition to the new Power Dock 2 is the on-board ADC that allows the Omega to measure the voltage level of an attached LiPo battery. This will give you a better idea of how much juice is left in the battery! As a result of the ADC, we were able to free up GPIOs 18 and 19, so they are now available on the Expansion Header!

The original Power Dock is on the top and the Power Dock 2 is on the bottom! Spot the 10 differences!

To read the battery level, you’ll need to install the power-dock2 package:

opkg update
opkg install power-dock2

And you are all set! To check the battery’s voltage, issue the following command:


If you are familiar with the Power Dock, you would notice the battery level LEDs will turn on and the voltage will be read out on the terminal screen:

root@Omega-F04D:~# power-dock2
Battery Voltage Level: 4.29V

The Power Dock 2 is now available for pre-order on the Onion online store! We expect to start shipping in the first week of October.
