These are pin compatible with SD cards, and are just half the length

They just slot right into an unmodified Pi and sit more or less flush with the edge:


Now that you mention it, I am sure I once read an article confirming that was indeed possible... perhaps only with certain brands though...

Caveat Emptor!
I think MMC cards are limited to 1-bit wide transfers (SDCARDs usually support 4-bit wide transfers) so the MMC card is likely to be slow.Montala wrote:This looks like an excellent solution.
Has anyone else tried it, and if so, are there any downsides to the idea?

Nice thought anyway!

Something like this, maybe?Dilligaf wrote:Someone needs to manufacture and sell a "MicroSD Pidaper", basically a half height micro sd adapter, then a micro sd would sit flush.
That does indeed look VERY interesting!azerty wrote:Something like this, maybe?Dilligaf wrote:Someone needs to manufacture and sell a "MicroSD Pidaper", basically a half height micro sd adapter, then a micro sd would sit flush.
Cool, that would work. Ideally the micro sd slot would be rotated 90 deg counter clockwise from the pic in order to make removal easier. Maybe raised enough that the socket overhangs the end of the sd socket and remains flush with the side of the board.azerty wrote:Something like this, maybe?Dilligaf wrote:Someone needs to manufacture and sell a "MicroSD Pidaper", basically a half height micro sd adapter, then a micro sd would sit flush.
I made this to go with an add-on board I'm making that has IO connectors hanging off the edge, which prevent the use of a full sized SD card. There's nothing proprietary about it, you can find specs for SD cards online with a bit of searching, so it was pretty easy to make.Montala wrote:That does indeed look VERY interesting!
Is it a proprietary device, or a purpose made 'one off'... or just a clever bit of 'Photoshopping'?![]()
Please tell us more!
The adapter is a bit loose due to being a little thinner and narrower than it should be, but otherwise I haven't run into any issues using it. What kind of problems with micro adapters did you read about?clickykbd wrote:I thought I read that micro adapters were problematic in general... i assume this one is not! Tell us more. Stop being a tease.
It's certainly possible, but it'll be a bit tricky. Micro SD cards are 15 mm long, and there's only 14.5 mm from the top of the socket to the edge of the board.Dilligaf wrote:Cool, that would work.

Well found!bircoe wrote:How bout these?
Little bit expensive as they're for the Apple brigade but they certainly look the goods!

I have also been advised that "The only difference between the "standard" and "pro" models is the width. The Pro model is ever so slightly wider (about 1.5mm or so) at the front.bircoe wrote:The Pro ones have round corners on the end piece where the air ones are right angles...
I see no reason why it wouldn't work in the Pi, on the electrical front it should work in any device that accepts an SD card... however there would be obvious physical issues with using these in other devices that stick to the SD standard.
What do you mean? Any links to this kind adapter?wolfgangmob wrote:Another option is a combo adapter for micro SD to SD/USB then just cut off the USB side of the adapter.
