Hi,
Last evening I hand soldered a SMD MicroSD Module PCB. The MicroSD Module enable easy connection of MicroSD cards to 5v Microcontrollers. It has on board 3.3v LDO Regulator, 5v to 3.3v i/o converter chip, Indicator LEDs (Power and Activity), SD Pullup resistors, Inductor for clean Hot-swap, Filter capacitor etc. The board is built on hight quality double layer FR4 board.
You can check out the first photos here!

Great ..! it will be a great help to starters like me ..!
Thank you
Thnx for that.But it will be a great help if u upload a tutorial for micro sd interfacing.
Hi Avinash, good that you made this available, at a low rate, as importing was costing much. Lots of users of my blog have been asking. I’ll put up a link to this product in my post.
For those who are new to microSD interface, you can visit my blog-article for the tutorial and code libraries: http://www.dharmanitech.com/2009/01/sd-card-interfacing-with-atmega8-fat32.html
It is more helpful if
You upload a tutorial for micro sd interfacing to AVR uC.
I just looked up the shop, it’s not listed there yet. When is it expected to be on sale?
@ Mr. Dharmani,
They are not still mass produced. The one shown above was hand soldered by me.
Don’t worry. I an Gifting you one of the module with your today’s Order!
Hey, thanks a lot!!
hey av,what about the sd card interfacing tutorial.you have told you were building it,when it will come.expecting a lot from you.thnx.
@Sayantan,
Sorry for breaking promise. But I am tight on schedule don’t get much free time. So I cannot promise when it will come. Right now I am working on tutorials on GLCDs.

What is pin 6 or CD on module ?
CD = Card Detect!
witch pin in the microsd is cd
Hey Avinash,
Your work is worth admiring!
Can you please include a tutorial for interfacing micro sd card with atmega32? It will be of great help if you do so.
Hoping for a positive reply.
