Yuan SC400N4 M2 SDI M.2 SDI Frame Grabber with 4 x 3G-SDI Inputs at 1080p60
M.2SC400N4 M2 SDI Overview
A vehicle or drone ground station with four SDI cameras needs every feed recorded, often by a compact computer with an M.2 slot rather than a PCIe slot. The SC400N4 M2 SDI is Yuan’s 4-channel M.2 SDI frame grabber for that job, with four 3G-SDI inputs on a 22 x 80 mm module.
Every channel captures at up to 1920 x 1080p at 60/50 fps, and the card also accepts 1080p30, 1080i, 720p and SD-SDI. Audio arrives as four stereo embedded channels. 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 M.2 2280 module uses an M key and runs PCIe x4. 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 SC400N2 M2 SDI captures two SDI feeds and adds loop-through outputs, and the SC400N4 SDI puts four SDI inputs on a full height PCIe card.
Yuan lists driver support for Windows 7, 8, 8.1 and 10, Linux 2.6.14 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 22 x 80 mm, and the host needs an M key M.2 slot with four PCIe lanes to run it at full width.

Official Yuan UK Distributor
Things Embedded is an official Yuan UK distributor, supplying the SC400N4 M2 SDI configured for UK broadcast and vehicle projects. Within the Yuan range the SC400N2 M2 SDI captures two SDI feeds with loop-through outputs, and the SC400N4 SDI puts four SDI inputs on a full height PCIe card.
As a 4-channel SDI card the SC400N4 M2 SDI sits among our M.2 capture cards and our SDI video capture cards. Where four SDI cameras must be recorded from an M.2 slot, this is the model to specify. It uses the same Yuan Windows and Linux SDK and DirectShow and V4L2 support as the models above.
