@Cameron-Spitzer said in Is Omega2 usable without a dock?: Next I need to learn how to control suspend, hibernate, and resume, and take interrupts on I/O pin transitions. Wake from suspend on an I/O pin change would be really nice. That was pretty easy on Raspberry Pi and Arduino (interrupts only), just have to find the docs. I'm afraid Omega2+ doesn't have suspend, hibernate, ... Power Modes - it can be Power On or Power Off only. Probably you have already known we have some info about Omega2(+)'s SoC Mediatek MT7688 Datasheet About GPIO Interrupts: https://github.com/OnionIoT/gpioIrq Omega2 current defects (Oct 2017) >> section GPIO Interrupts There isn't any too much progress - I think.

@Pavel-Metrokhin Onion Omega2 Documentation Using the Power Dock 2 Stationary Mode (this is one of the three different modes) The Power Dock will still work when the battery is disconnected and the Power Dock is receiving power just from the Micro USB cable. Checking the Battery Level The power-dock2 application allows you to turn on the Battery Level indicator LEDs as well as output the current voltage of the battery on the screen. You can monitor the voltage on the command line while it is in Battery mode or Stationary mode. I think this remote sensing is one of the few unique features in the World of the Power Dock 2
