hi
I have micro SD card module on my RAMPS1.4 and this thing doesn't work since I got it first time. I decided to fix it, and tryin to test it on another arduino mega But I cannot be sure about pins.
Looks like this is exactly same module I have

But no pin labels on pcb. Anybody can tell me which pins are use and what are those?
