This SD/MMC card double side breakout for your application data logging and acquisition. It allows you to breakout the mircSD/SD/MMC socket to a standard 2.54mm-pin header. It is used in SPI Mode interface.

The module can work with 5V or 3.3V power supply, and both 5V/3.3V IO operation level. It can be controlled directly by a wide range of microcontrollers. 

Note: If you use 3.3V power supply, please switch to 3.3V side.

Dimensions: 31 x 45 mm
