The Stackable SD Card Shield is a stackable design for Arduino SD / TF card expansion boards. It incorporates SD / TF read and write functions directly into the Arduino board expansion.

• Only Support TF/SD cards which support ISP modes.
• Only use the arduino SPI interface, may conflict with other shields which will also use the SPI.
• Extra Uart and IIC interface, four pins PH2.0 connectors
• Can switch between large CD card read slot or small micro SD card read slot.

The package includes the main PCB board, two PH2.0 connecting cables, and two not-soldered Arduino special pin headers.

Usage:

• For default arduino official SD library, only need to change CS pin to 10. NOT default D4 in sketch.
• Notice switch to “big” or “Micro” for either SD card or microSD card.
