12.5-inch 4K IPS Touchscreen Display Works with Raspberry Pi 4B and other 4K SBC’s

There are plenty of displays for the Raspberry Pi boards, but if you are looking for a high-resolution display with capacitive multi-touchscreen it may be challenging to find. DFRobot may have what you are looking for though with a 12.5″ 4K IPS touchscreen display.

The company says it’s compatible with Raspberry Pi 4B SBC, but since it comes with a mini HDMI input port, it should really work with any 4K capable SBC’s or computers.

I understand you’ll need to connect three cables to the display: an HDMI cable for audio and video, one USB cable for touchscreen, and another USB cable for power. In theory, it should be possible to have both touch and power via a single USB cable, but maybe some boards, including Raspberry Pi 4B, don’t provide enough power over USB-C.

DFRobot says both Windows and Linux are supported, so I suppose drivers may be required for the touchscreen function, while HDMI input should really be OS-agnostic, but there’s no Wiki that I could find. For reference, Waveshare sells a similar 12.5-inch Full HD touchscreen display, and besides changing config.txt, nothing else appeared to be needed to work with Raspberry Pi.

The display ships with 2x male to male USB-C cables, a USB Type-C to USB A cable, an HDMI to mini HDMI cable, a micro HDMI to mini HDMI cable, a UL certified power adapter and a protective cover. 4K resolution does come at a cost though, as DFRobot 12.5-inch 4K IPS touchscreen display is sold for $289 plus shipping.
