$10 HDMI to USB 3.2 video acquisition board is based on MS2130 chip

We’ve just written about an open-source hardware Allwinner V851S camera board from YuzukiHD, but he/she has made another interesting board with the YuzukiLOHCC PRO HDMI to USB 3.2 video acquisition board based on MacroSilicon MS2130 HDMI to USB chip, as well as MS9332 one-to-two active splitter, and MS8003/MS8005 microcontroller.

YuzukiLOHCC PRO stands for Yuzuki Loop Out HDMI Capture Card PRO, and there are two HDMI ports, one for input and one for output, as well as a USB Type-C port to connect to the host and capture the video input.


YuzukiLOHCC PRO key features and specifications:

  • Main chip – MacroSilicon/UltraSemi MS2130 USB 3.2 Gen 1 high-definition video and audio acquisition chip
  • MCU – MacroSilicon MS8005/MS8003 8051-core MCU
  • Splitter – MacroSilicon MS9332 one-to-two active splitter
  • Video Input – HDMI up to 4Kp30 or 1080p60
  • Video Output – HDMI 2.0 YCbCr420 4Kp60 loop out, 10/12/16-bit deep color, adaptive input equalization, pre-programmed HDCP keys, embedded EDID RAM
  • Host interface – USB Type-C USB3.2 Gen 1 interface compatible with UVC 1.0
  • Capture
    • YUV422 & MJPEG USB video output up to 1080p60
    • Audio capture supported

Since the board is UVC compliant, it can work with most operating systems including Windows XP/7/8/10, Android 5.0 and up, macOS, and Linux. Capture can be done with OBS Studio, FFmpeg, and other programs.

The board has been designed with EasyEDA, and you’ll find the hardware design files, MS8003/MS8005 firmware (binary only), and some more documentation including the list of resolutions and refresh rates supported for USB capture on GitHub. There’s additional information on the OSHWHub website but in Chinese only. A short video demo of the board in action can be found on Twitter.

The board is not for sale, so you’d have to build it yourself. The tricky part might be to obtain the MS2130 chip, as it seems rather new, and hard to source based on comments on Twitter. If you don’t feel like making your own board, and would prefer to buy something to use, there should be hope as we’ve previously seen cheap HDMI to USB 2.0 video capture dongles based on the previous generation MacroSilicon MS2109 chip, and it’s probably just a question of time before similar devices based on MS2130 come to market. There may not be any HDMI loop out port though.

Thanks to TLS for the tip.
