I bought this SD card break out board years back. Was wondering if there's any documentation on it.
There's a single chip on it: AMS1117 (linear regulator) and the board has a SPI interface. The board doesn't have a name so I don't really know what to google (some googling led me to its amazon page)
D. Haigh in the Amazon product comments mentioned an adafruit tutorial but I don't think it's the same card module. He said it ought to work with the "old SD card library" but I'm not sure where to get that.
It's a pretty cheap board and I'd have no qualms tossing it. Do you think it's more trouble than it's worth to try to work with this thing?
I believe the module is the one shown in the attached schematic. It has no level shifting circuit, so the three SPI output lines of a 5V Arduino would be connected directly to the relevant SD card pins while the card itself is powered at 3.3V. It's possible some SD cards will tolerate that, but they aren't required to. So if your Arduino is 5V, you shouldn't use the module. Instead, you could get one of these, which does have a level shifter:
