SD to microSD Card Extender

Move an awkward card slot to somewhere easier to reach with this flexible SD to microSD extender. It gives you a long cable with a pseudo-card on one end and an SD card socket on the other, so you can plug into the host device and mount the socket wherever it is more convenient.

It is a handy hack for tight builds and hard-to-access card slots in 3D printers, single-board computers, data-logging kits and similar projects. It can also help reduce wear and tear on the original socket by letting you access the card externally.

The socket is push-push: insert the card to lock it in place, then press it again to release. A small pictogram on the socket shows the correct card orientation.

Adafruit tested this with a Replicator 3D printer and a Raspberry Pi Linux computer and found it speedy and error-free, but it is still a hack. High-speed or electrically noisy environments may not work reliably, and systems that rely on mechanical card insertion for mount/unmount detection may be confused if the card is electrically removed without the host seeing a mechanical removal.

Specifications:

• Cable Length: 23cm / ~9"

Best suited to systems where you can force a mount/unmount in software, or where the card is only changed while the device is rebooted or powered down.
