About

Ultra low cost Loop Out HDMI-USB Video Acquisition (HDMI Capture Card) based on MS2130 and MS9332 + MS8003

MS2130 is a USB 3.2 Gen 1 high-definition video and audio acquisition chip, which is internally integrated with USB 3.2 Gen 1 Device controller, data transceiver module, and audio and video processing module. The MS2130 can transmit the audio and video signals input by HDMI to a PC, smartphone, or tablet for preview or collection through the USB 3.2 Gen 1 interface. The MS2130 output supports YUV422 and MJPEG modes, and is compatible with Windows, Linux, Android and Mac OS systems. Support OBS Studio, Camera, and FFmpeg.

Order a PCB

Here I suggest using JLCPCB to make PCB (my template is also made by JLCPCB). Please note that the impedance needs to be 3313, and the PCB thickness needs to be 0.8mm to install the clamp-style TypeC connector

Flash Firmware

USB Flash

Using ms-tools from @BertoldVdb

./cli --log-level=7 write-file --verify FLASH 0 YuzukiLOHCCPro.bin

SPI Programmer

Use an SPI NOR flasher to flash the firmware to the NOR Flash before soldering.

(Only one of U4 and U8 needs to be mounted, adding two SPI NOR pads are drawn to be compatible with different types of materials)

eeprom

Unfortunately, I couldn't find a public version of the MS8003 code, but it's not expensive to buy a pre-programmed set
