Product Description:

SD/MMC Card Adapter
This is a simple SD or MMC adapter card. It allows you to interface with any microcontrollers. It is perfect for mass storage, WAV/MP3 player and data logging. The adapter breaks out the SD/MMC socket to a standard 0.1" 11-pin header. It can be plug directly into breadboards. This adapter features innovations that set it apart from other SD card adapter. Innovations feature like on-board card detect LED, Push-Push socket, and 3.3V regulator. Which mean either 3.3V or 5.0V microcontroller can be connected directly with the board. You can even use this 3.3V to power external circuits up to 250mA.

SD cards offer an inexpensive, flexible and reliable way to bring data logging and data storage solutions to your electronic design projects.

Pinout:

VIN: Input power to the SD card (3.3V to 6.0V)
GND: Common (Connects to the housing of the SD socket)
3V3: Output voltage from the on-board 3.3V regulator (250mA)
NC: Connect to pin 9 on the SD card (not used in SPI mode)
CS: Chip select
DI: Serial input data
SCK: Serial clock
DO: Serial output data
IRQ: Interrupt request, connect to pin 8 on the SD card (not used in SPI mode)
CD: Card detect (active low)
WP: Write protect
