Pengo HDMI Grabber Wiki

The unofficial technical reference for the Pengo 4K HDMI Grabber

B&H SKU: 8RGRA-H01HU4T0PE  ·  USB ID: 1e4e:701f (Cubeternet)  ·  Protocol: UVC 1.0 + UAC

Pengo HDMI Grabber

What is it?

A compact external capture box that takes an HDMI 2.0 4K @ 60 fps 4:4:4 input from any source (game console, camera, PC, Raspberry Pi, etc.) and exposes it to a computer as a standard USB Video Class (UVC) webcam at up to 1080p60.

Because it speaks plain UVC + USB Audio Class, no driver installation is required on any modern Linux, macOS or Windows host — plug it into a USB 3.0 port and it appears as /dev/video0 (Linux), a webcam (macOS/Windows), and a USB audio device.

Use the included USB cable

The USB-A cable shipped in the box is "proprietary" per the manufacturer. Plugging the grabber in via a hub or a random USB-A cable will degrade bandwidth and may prevent the device from enumerating. A short USB-A→USB-C adapter at the computer end is fine.
