MicroSD Card Breakout Board

MicroSD memory cards (originally known as TransFlash) provide a compact and inexpensive way to add gigabytes of non-volatile storage to a project. All SD cards support communication over the SPI (Serial Peripheral Interface) bus, making it straightforward to interface one of these cards with an SPI-capable microcontroller. This simple board breaks out the pins of a microSD card connector to a 0.1″ pin spacing that is compatible with standard perfboards, solderless breadboards, and 0.1" connectors.

All of the microSD card’s power pins and all of the signal pins necessary to interface with the card through SPI are available along the right side of the board. The left side of the board exposes duplicate power pins, along with two additional signal lines (DAT1 and DAT2) that are not needed for SPI communication but are used in 4-bit SD bus mode. The DAT1 pin also serves as an interrupt pin (IRQ) in SDIO devices. (Note that if you are using this module in a breadboard, you might want to solder header pins into both sides of the board for added stability even if you only plan to use the SPI pins.)

GND (VSS)  :  Power and logic ground
VDD  :   Supply voltage (2.7 V to 3.6 V for standard microSD cards)
CD    : Card detect. When a card is inserted, this pin is floating; when no card is inserted, it is shorted to ground. A pull-up resistor can be used to pull the line high when a card is present.
