This board is a unique board recommended by a SparkFun customer. When playing with SD, you sometimes need to view what the SPI traffic is doing, whether for hacking or debugging. The SD 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 a SD card into the SD holder, simple as that.
Note: This product is a collaboration and a portion of each sale goes toward the designer for product support and continued development.

Jargon buster
Plain-language definitions for the technical terms used above.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
