Hi Juraj,I found a Sparkfun Sd adaptor, link is below. Will it work for me?
SparkFun SD / MMC Card Breakout - Uygun Fiyata Satın Al! | DomiRobot.com
Also, how can i fix my sd card adaptor i am using now? If you have any tutorial about this, could you please send me a link.
Thank you.
this is not an adapter. it is only a holder. it can be used only with a 3.3V MCU. 5V MCU would damage the SD card.
the general description of the fix is to cut the trace (or remove a resistor) between the PCB pin labeled MISO and the level conversion IC and then bridge the card holder MISO pin with the PCB MISO pin (or with the trace to it). MISO is "master in slave out" so 3.3 V of SD card to input pin of MCU. the MCU will read 3.3 V as HIGH.
I didn't after my adapter yet.
