Works Great
I bought this today and it worked great out of the box. The other review about the pins being mislabelled must be a different product. Mine has these pins in order top-to-bottom: GND, +3.3, +5, CS, MOSI, SCK, MISO, GND The MOSI goes to D11, SCK to D13, and MISO to D12. I chose D4 for CS but you can pick whatever you find suitable. I powered with 5V and only used one GND (you can use both if you need the extra grounding). There’s 2 rows of pins but only one is needed for use, the other is for daisy chaining them or something. I just used the standard “SD” Arduino library and was able to read and write first try.
