    Micro SD Card Adaptor HELP

    Hi all,
    I'm a student and am in a class in which I have to create a circuit board. For my project, I need to use the micro sd adaptor https://www.pjrc.com/store/sd_adaptor.html .

    I've been using the program Altium to create the board, but in Alitum you need to search for parts you want to put on your board with a manufacturing number (listed as Digi-Key Part Number here) https://www.digikey.com/product-deta...ource=octopart

    I also need to have a pin configuration to see what all the pins do pg 5 as an example of what I mean http://www.ti.com/lit/ds/symlink/ads1299-6.pdf .

    I can't seem to find any of that information on the pjrc website and i can't find the part on any other websites that I know of (DigiKey and Mouser).

    ANY information will be more than helpful. I apologize if I'm not using the correct terminology or if I am missing something very obvious, I've never done anything with electronics before and honestly I have no idea how any of these things work, my group just told me to figure it out and that's what I'm trying to do.

    THANK YOU

    Other than designing a board to connect this board to the Teensy (and of course ultimately soldering stuff and a micro SD card), you don't need any additional components. The board has all of the appropriate circuits (*). There are simpler micro SD cards, where you would need to add resistors, capacitors, diodes, etc.

    Generally, you would want to do things on a breadboard first, and make sure you understand the wiring, etc. Then it should be fairly simple to move it over to the board.

    * in some cases, where you are sharing the SPI bus with other devices, particularly high speed displays that are optimized for Teensy, it might be advisable to add a 2.2K pull-up resistor on the SS pin (sometimes called CS instead of SS).


    I will leave it as an exercise which pins on the Teensy to use.
