Yuan SC550N2 M2 SDI M.2 SDI Frame Grabber with 2 x SDI Inputs at 1080p60
M.2SC550N2 M2 SDI Overview
Two SDI cameras on a vehicle, a small studio kit or an inspection rig often feed a computer with no room for a PCIe card. The SC550N2 M2 SDI is Yuan’s 2-channel M.2 SDI frame grabber, taking both 3G-SDI feeds through one 22 x 80 mm card in an M.2 socket.
Two SDI inputs run as separate capture channels. It accepts 3G-SDI at up to 1920 x 1080p at 60/50 fps, HD-SDI at 1080p 30/25/24 fps, 1080i 60/50 fps and 720p 60/50 fps, and SD-SDI at 480i and 576i. Colour formats cover 4:4:4 RGB24 and RGB32, 4:2:2 YUY2 and 4:2:0 YV12 and NV12 at 8 bits, giving software a choice between full colour detail and lighter frames. The card also crops, scales and deinterlaces on board and detects the incoming signal automatically. Each channel carries SDI embedded audio, sampled as 16-bit stereo at 32 to 48 kHz.
The card fits an M.2 Type B/M socket at 2280 length and runs over a PCIe x1 link, with no on-board encoder. Windows and Linux SDKs cover custom applications, and DirectShow and V4L2 support lets vMix, OBS, Zoom, Teams and similar software open it directly. The SC550N1 M2 SDI is the single-input 2260 card, and the SC550N4 M2 SDI takes four SDI feeds on the same 22 x 80 mm size.
Supported systems are Windows 7, 8, 8.1 and 10, 32-bit and 64-bit Linux from kernel 2.6.14, Linux on ARM, and NVIDIA Jetson TX2, Nano, AGX Xavier and Xavier NX. The board measures 22 x 80 mm and brings each SDI input out on a cable to a BNC connector. Yuan lists multi-device and multi-instance support for hosts that take more than one card.

Official Yuan UK Distributor
Things Embedded is an official Yuan UK distributor, supplying the SC550N2 M2 SDI for UK broadcast and embedded video projects. Within the Yuan range the SC550N1 M2 SDI is the shorter single-input card, and the SC550N4 M2 SDI doubles the channel count for multi-camera systems.
With two SDI channels the SC550N2 M2 SDI sits among our M.2 video capture cards and our SDI video capture cards. Where two SDI cameras feed a compact PC with a free M.2 socket, this is the model to specify.
