MicroSD Module

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!

    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
