Worked OK no issues, didn't use a level shifter and it hasn't blown up yet, though I did connect it to a 3.3v supply from my Arduino, whether that makes a difference or not I don't know.
The card I used was an old Sandisc Ultra 2 1.0gb card which I used in a digital camera many moons ago (so you can tell how old it was!). Card details are
- Card type: SD2
Blocks x Cluster: 8
Total Blocks: 1975552
Volume type is: FAT32
Volume size (Kb): 987776
Volume size (Mb): 964
Volume size (Gb): 0.94
Worked with both of the examples supplied, and with the "Cardinfo" sketch from the Arduino IDE examples folder. Also read and displayed text files from my laptop.
Probably worth noting that you are restricted to the old "8.3" format of file labelling (A C or C++ restriction I believe)!
Thanks for a really useful product -
