This Instructable tells you how to make an SD adapter which will enable you to add up to 2GB of memory to your microcontroller projects. It includes a card inserted LED and is used in SPI mode.
A kit inluding all the parts necessary to build the SD Card Adapter can be purchased here. If you wish to do so, you can also make your own version without purchasing the designated kit, but getting the SD card slot may be challenging, as there are many different versions. Purchasing the kit, however, provides much greater support if you have any problems or questions.
This project requires approximately 30 minutes to assemble, and some parts may be a bit challenging to the beginner in soldering.
If you have any questions or comments, feel free to add them in the designated area below.
Without further adieu, plug in your soldering iron and get all the parts together. For those of you who are building your own version, check the link given above and on the bottom left you will find an option that says "parts list." Selecting that will show a menu of all the parts required to make it.

Signing UpStep 1The Hard Part First....
This is one of the hardest parts of the project because it requires some "surface mount soldering." (note the quotations) Now, follow the steps shown in the image notes in order to get the SD slot on your PCB.

I haven't had much time to post anything on Instructables lately, but I think I am going to be making a MicroSD version of this, which will probably include a circuit board etching tutorial.
I will hunt down the schematic and post it here so you can see what the pinouts are. Lately I have been doing a lot of pcb etching and plan to make an instructable on that. :)
Here's the pinout:
SD adapter header | | | | | | | | | | | |
cs di sck do gnd +3.3v
Abbreviations (if you don't already know):
CS- Chip Select
DI- Data Input
SCK- Clock
DO- Data Output
GND- Ground (obviously)
This does require a 3.3 volt regulator, because it does funny stuff if it's on 5 volts.
If you need a bit more info on the pinouts of an SD card, look at this site.
Good luck.
I do know how to format an SD card to FAT16, which is definitely what you will need for any mcu.... What size SD card are you using?
