Yuan SC400N1 MC AIO Mini PCIe HDMI and SDI Video Capture Card with 1080p60 Input

Many embedded boards and small fanless PCs keep a Mini PCIe socket free long after their PCIe slots have gone, and that socket is often the only way to add a camera input. The SC400N1 MC AIO is Yuan’s Mini PCIe HDMI and SDI video capture card, sized at 30 x 50.95 mm.

The card has one capture channel and accepts up to 1920 x 1080p at 60/50 fps on either input, with 1080i, 720p and SD signals also supported. Audio is taken from HDMI or SDI embedded streams, and analogue left and right are available through a wafer connector. Capture and preview formats are RGB24 and RGB32 at 4:4:4, YUY2 at 4:2:2, and YV12 and NV12 at 4:2:0, all 8-bit, so host software can take frames in the format it already uses.

The card runs PCIe x1 over the Mini PCIe connector. On-board processing covers cropping and scaling, automatic signal detection and deinterlacing, and the card captures VANC data alongside video and audio. There is no hardware encoder, so any compression runs in software on the host. Yuan supplies a Windows and Linux SDK for custom applications, and the card works with DirectShow and V4L2 software; Yuan’s compatibility list names vMix, OBS, Zoom, Skype, Teams, Discord, Slack, Cisco Webex and GoToMeeting. The SC400N1 MC SDI is the SDI-only Mini PCIe card with loop-through, GPIO and a watchdog, and the SC400N1 M2 AIO puts the same two inputs on an M.2 2280 module.

Yuan lists driver support for Windows 7, 8, 8.1 and 10, Linux 4.8 or higher in 32-bit and 64-bit builds, Linux ARM, and NVIDIA Jetson TX2, Nano, AGX Xavier and Xavier NX modules. Yuan lists multi-instance and multi-device support for systems that run more than one capture session or card. The card measures 30 x 50.95 mm, the full Mini PCIe size, so it fits the standard socket on embedded boards.
