LORDWORLD SD Male to Female Extension Cable 100mm UHS-III

SKU CH-HEQ2-0KFFG

A 100 mm flexible SD male-to-female extender supporting UHS-I, UHS-II and UHS-III speeds up to 321 MB/s for development boards and equipment

  • Extends SD cards 100mm for flexible placement in tight devices
  • Supports UHS-I speeds up to 104MB/s for reliable data transfer
  • Handles UHS-II and UHS-III bandwidth up to 321MB/s for high-performance cards
  • Tested at 250MB/s with UHS-II cards confirming real-world throughput
  • Male-to-female connector design enables easy extension without signal loss

SD Card Extension for Development Boards

This 100mm flexible cable connects an SD male plug to an SD female socket, letting you relocate the card slot on a ROCK Pi 4, Raspberry Pi or similar SCM board. It accepts SD, SDHC and SDXC media and is rated for UHS-I, UHS-II and UHS-III signalling. The short length keeps signal integrity high while giving enough reach for panel mounting or enclosure routing.

Signal Integrity at UHS-III Speeds

The extender carries the full UHS-III bus up to 321MB/s and has been tested with a UHS-II card at 270MB/s, delivering 250MB/s in practice. UHS-I modes run at their rated 104MB/s and 52MB/s without degradation. Gold-plated contacts and a shielded flat ribbon reduce crosstalk, so the card performs as if seated directly on the board.

Replaces Direct Board-Mount Slots

Use this cable when the on-board SD connector is inaccessible or when a ruggedised panel-mount slot is required for field service. It is not suited for permanent outdoor exposure or high-vibration environments without additional strain relief. The jump is worth it whenever mechanical constraints prevent a straight card insertion.

Questions about this item

What speed does the UHS-III interface actually cap at with this 100mm extension?

The cable supports UHS-III full speed up to 321MB/s; in testing a UHS-II card at 270MB/s delivered 250MB/s through the extender.

How much clearance does the 100mm flexible cable need behind the device?

Total length is 100mm including both SD connectors, so allow roughly that depth plus the card thickness for a clean bend radius.

Which way round do the SD male and female ends go when installing it?

Plug the SD male end into the host slot first, then insert the SD card into the female end; reversing them breaks the signal path.
