SMUGDESK TF MicroSD Female to Male Extension Adapter UHSIII UHS3 UHS2

SKU CH-A361-8BEXW

Extends MicroSD card connections with UHS-III, UHS-3 and UHS-2 support for testing and embedded development

  • UHS-III speeds maintained through extension
  • Extends MicroSD connection without signal loss
  • Plug-and-play female-to-male adapter design
  • Ideal for hardware debugging and DIY projects
  • Compatible with SBCs, cameras and industrial gear

MicroSD Extension Adapter

The SMUGDESK TF MicroSD Female to Male Extension Adapter connects a MicroSD card to a device over a short distance while preserving full signal integrity. It is built for engineers, developers and hobbyists who need to test or debug card interfaces without soldering directly to a board. The plug-and-play design fits single-board computers, cameras and industrial modules that use standard MicroSD slots.

UHS-III Speed Support

The adapter handles UHS-II, UHS-III and UHS3 protocols so the host can negotiate the highest speed class the inserted card supports. Bandwidth scales with the card itself; a UHS-I card will run at UHS-I rates while a UHS-III card can reach its rated ceiling. There is no active circuitry to boost performance beyond what the media and host controller provide.

DIY Testing Utility

The compact form factor lets you extend the card slot outside an enclosure for quick swaps during firmware development or hardware validation. It removes the need to repeatedly insert cards into tight internal sockets on Raspberry Pi, Arduino or custom embedded platforms. No drivers, software or external power are required — only the mechanical extension the adapter supplies.

Questions about this item

Will this adapter maintain UHS-III speeds when I connect my existing UHS-III MicroSD card to a Raspberry Pi?

Yes, the adapter supports UHS-III, UHS-3 and UHS-2 protocols, so your UHS-III card will run at its rated speed through the extension.

How can I verify the adapter is passing data without errors after I plug it into my single-board computer?

Run a read/write benchmark or checksum test on the inserted MicroSD card; consistent throughput at the card's rated UHS class confirms the extension is working correctly.

Does the package include a MicroSD card or only the female-to-male extension adapter itself?

Only the TF female to MicroSD male extension adapter is supplied; a MicroSD card must be purchased separately.
