Experimenting with SD cards

Hi All,

Which Arduino board would you recommend for experiments in interfacing to an SD card? I'm interested in exploring how to write to the card, writing a filesystem driver etc. I'd ideally like to buy a kit I can build which already has an SD card slot.

Thanks, Sean

Well, i guess you can go with the 2009 board or any other compatible system. So far only minor differences seem to happen in between the various releases. What i would recomment though is replacing the Atmel 168 with an (Adaboot?) Atmel 328p which has a bit more space for programming, which is essential for the idea of yours.
From what i know there is no premade Arduino board with an SD Slot - so the best thing for you would be to grab either a SD breakup board or ‘build your own one’.

Some things for you to look at/read
SD Card 101 for Arduino: http://www.arduino.cc/cgi-bin/yabb2/YaBB.pl?num=1235125412
Arduino with 328p: http://www.adafruit.com/index.php?main_page=product_info&cPath=17&products_id=50
SDCard holder: I got mine from FCI COnnector as (free) sample. I tried that way because i havent found any card holders which were sold at reasonable prices. Alternatively you could strip an old card reader off its holder.

Hope i could help you

Thanks for the helpful reply. So it sounds like all I need for my experiments are an Arduino main board, an SD card socket and the resistor dividers shown on the circuit at http://img441.imageshack.us/img441/2391/schematicuo7.jpg ?

I guess so - although a bunch of LEDs would it make more blinky - hence funnier ^^

Old Floppy Connector?

wow, now that is some interestering idea :0)
