🤨 FAQs
Q: Is Extension Module v2 one product or two network versions?
A: It is one product. Both the 100M and 1000M Ethernet cards are included in the box.
Q: Which Ethernet card should I use?
A: Use the 100M card for all uConsole base boards. Use the 1000M card only if you have the uConsole Upgrade Kit and need gigabit networking.
Q: Do I need the HackerGadgets uConsole Upgrade Kit?
A: Only for gigabit Ethernet. The 100M card works without the Upgrade Kit. If you do not already have the kit, choose the bundle option or purchase the kit separately.
Q: Can I use this together with the 4G or LTE module?
A: No. This module uses the uConsole expansion slot, so it cannot be used at the same time as the 4G or LTE module.
Q: Does the target device need software or drivers?
A: No. The KVM function uses USB HID keyboard and mouse emulation, so the target device does not need special software for keyboard and mouse control. Learn more about USB based KVM technology.
Q: Is the software open source?
A: Yes. The Openterface Connect Apps are open source and available on our GitHub repository.

Works flawlessly and makes the uconsole really useful!
Hard to install software and usb switching port does not work. Else a really neat package.
it was hard having the software to run.
the keyboard and mouse are not working.
there is a lag in hdmi input.
Great device for the on the go IT pro. I've found it super handy to have a KVM built into my daily carry. No more looking for a monitor or keyboard!
The HDMI only displays in a box on the UConsole. There is no menu to change app settings. No mouse control on either Windows or Linux Host. Text is upside down on the port cover.
Thanks for reporting this and sorry for the trouble you’re experiencing. We’ll make sure to get this sorted.
Regarding the text on the port cover: the orientation was designed so that when you hold the uConsole and look down at the ports from the top, the text is readable. It may appear upside down depending on the viewing angle, but this was intentional to make port identification easier.
For the mouse control issue, could you please share:
Which Linux distribution you’re using on your uConsole?
Is it running on the CM4 module?
This will help us diagnose the problem accurately.
