  • If I'm correct, as the Arduino pins outputs 5V and the MMC/SD card needs to be operated at about 3.4V, MISO does not need a voltage divider, while MOSI does. According with the connections scheme you suggest, CMD/PIN 11 is MISO (it doesn't need pull down resistor) and D0/PIN 12 is MOSI (and thus it needs the pull down resistor)?

No public wish lists :(
