Show HN: Raspberry Pi with portable touch monitor with a single USB-C cable
getubo.comRaspberry Pi only exposes HDMI display ports.
That means every time I want to connect a monitor to the Pi I have to power my monitor using a separate power adapter.
I use portable monitors a lot and wished I could just use one USB-C cable to both power the monitor and send video signals.
One of my portable displays also has touch support which works when I connect it to my Macbook.
I wanted to also get touch display working with a single USB-C cable setup. This would allow me to put my Home Assistant dashboard on it and control everything with touch.
So I embarked on a prototyping journey and got this setup working.
I am designing a compact adapter board that will add this capability to Raspberry Pi 4 and 5.
I am documenting my design and prototyping journey on my blog and Youtube. This design will be open source with KiCAD files published.
