SD Card Extension Cable 25cm FFC

The SD2SD is a 25cm SD card extension cable designed to relocate an SD card slot when the original port is difficult to reach. One end features a full-size SD connector that plugs into the target device, while the other end is a screw-mountable SD card holder measuring 36 × 29 × 3.8 mm. The cable itself is a flexible flat FFC ribbon, which allows routing through tight enclosures and reduces mechanical stress on the connectors. The holder is made from FR4 board material, providing rigidity for permanent panel or wall mounting. This SD card extension cable operates at 3.3V DC and is plug-and-play, requiring no drivers or software configuration. It is commonly used in DIY electronics, industrial monitoring systems, Raspberry Pi and Arduino projects, 3D printers, and surveillance camera setups where the memory card must remain accessible. Because the SD interface relies on high-speed digital signaling, the 25cm ribbon length is a practical balance between reach and signal stability; in sensitive setups, keeping the cable away from noise sources and ensuring solid connector seating helps maintain reliable data transfer. The screw holes on the holder allow the card slot to be fixed to a panel, keeping the memory card accessible for frequent replacement.
