This is a breakout board for the microSD socket that is not much bigger than your fingernail. Compatible with the SPI interface found on any SD card, this tiny form factor was created for cell phone storage and is perfect for your next MP3 project. The board comes fully assembled and tested.
This board was designed to be embedded and retain easy access to the microSD card. In the loaded position, your microSD, SDHC or SDXC card will be right on the edge of the PCB, allowing for easy push-to-remove access.
microSD TransFlash Board Pinout The silkscreen labels the pins in generic or SPI terms:
- CD — Card Detect
- DO — Data Out
- GND — Ground
- SCK — Serial Clock
- VCC — 3.3V Power (Voltage Collector Connected to Ground)
- DI — Data In
- CS — Card Select
Note: Per SD specification, you should use 3.3V for power and I/O. If you want to use it in a 5V system such as a "normal" Arduino, you'll need to add a level-translation circuit (or you may want to purchase the microSD Shield instead, which has a level translator built in).
