Sorry that should read a Leonardo arduino card, of course. Should I be worrying about this comment in the demo code? "If interfacing to the module with 5V DIO it is recommended that you level shift the 5V DIO down to 3.3V for the MOSI, SCLK, and CS pins. You can do this by using an appropriate level...

Re: SD Card Module (HCARDU0008)

I have just got one of these cards but I cannot get it to work - appears to be a faulty card. I am using the ARD_SD_CARD_MODULE_HCARDU0008_Write_Example code and have wired it correctly (checked and double-checked) but all I get is "Card failed, or not present". Faulty card? or is there something mo...
