It works well for what it is.
As people have said in the comment section, the card when inserted DOES NOT extend all the way to the edge, so don’t expect to embed this in an enclosure. This might depend on the exact card you’re using but I have two different cards here and neither of them reach the edge.
It would have been nice to see all SD card pins broken out, but for my purposes I only intend to use SPI mode and this board is great for that.

Just a simple breakout for a microhd socket with all the signals you need to talk to the card over spi.
does the job. works great.
would be nice if you added a 1uF or .1uF cap across VCC and GND. The spec for hooking up uSDs says to do this. Would be nice if you had a SMT cap on the next rev of the board.
just a thought.
I bought 3 of these breakout boards and fought with one for 2 days figuring that there had to be something wrong with my code. As it turned out the breakout board was faulty and as soon as I switched out the board everything worked great. I haven’t tried my third one yet.
I’m sorry to hear that you received a faulty board. If you’ll contact our tech support team, we’ll be happy to arrange a replacement or refund for you.
Had an application where I needed to add a uSD card to a Teensy 3.1. This allowed me to verify my PCB design. I was also able to start coding while I waited on OshPark to finish my boards.
If you have tried soldering wires onto a microSD card socket, well, forget it. Not impossible, but very, very difficult.
What this does is make it simple to attach a .1" header to the little board so it can be connected to a breadboard easily. It can also plug into a 6 or 7 pin female header - the CD pin in rarely used.
The microSD socket used for this is from conn4u.com and is very economical; as long as you want 3000 of them. If you were hoping on using the Gerber files for this for your own PC board, you will find them to be pretty useless because of the source of the socket. MicroSD sockets are not all that popular to have public PC board layouts for and they are complex and have pretty close tolerances. I understand why the conn4u.com part is used: it is pretty good and it is cheap if you are going to use a lot of them. I wish the manufacturers (Hirose, Amphenol, etc.) made available either nicer drawings or layout files for these things.
Very simple and easy to integrate.
Unfortunately this board did not work for us because only 6 of the 8 pins are brought out from the uSD socket.for wiring. We ended up buying the microSD sniffer board for our application.
Hi, Sorry to hear that this didn’t work for your needs. Please contact us if you would like to return it for a refund. We’ll be happy to help you out. https://www.sparkfun.com/returns
Having the option to install pull-ups on the PCB would be very helpful.
I’ll pass your comment along for future consideration if we revise this product. Thanks!
