FAQs

Q: How does the KVM Extension Board work?
It captures HDMI output from a target device and displays it on the uConsole. At the same time, the uConsole’s keyboard and trackball are used to control the target device via USB HID emulation.

Q: Can I use this with the 4G/LTE module installed?
No – this board occupies the same expansion slot. You’ll need to choose between cellular connectivity or KVM functionality.

Q: Is the software open source?
Yes! Firmware, drivers, and installation tools are fully open-source and available on our GitHub repository.
