MicroSD Module

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.

    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
