SD Card SPI Sniffer
When playing with SD, you sometimes need to view what the SPI traffic is doing, whether for hacking or debugging.
This SD SPI Sniffer allows you to hook up an external device, such as a logic analyzer or microcontroller, to view what signals are being passed back and forth. Insert one side into a regular SD socket and an SD card into the SD holder, it is just as simple as that.
This board is populated with this SD Card Socket.
