The SparkFun microSD Sniffer lets you tap into the SPI traffic between a microSD card and its host device for debugging or reverse engineering. Insert one end into a standard microSD socket and plug a microSD card into the onboard socket — all SPI signals are then broken out to an 8-pin 0.1″ pitch header for connection to a logic analyser or microcontroller.

Key Features

  • SPI Bus Sniffer – Passthrough design lets you monitor all microSD SPI traffic
  • 8-Pin Breakout Header – 0.1″ (2.54 mm) pitch for easy connection to logic analysers
  • Inline Design – Sits between the host socket and microSD card transparently
  • Standard microSD Form Factor – Compatible with any standard microSD slot

Ideal For

  • Debugging SPI communication with SD cards
  • Reverse engineering SD card protocols
  • Logic analyser capture of microSD traffic
  • Embedded systems development and testing
