This is a simple MicroSD adapter card, that allows you to interface with any microcontroller.
This is a simple MicroSD 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 MicroSD socket to a standard 0.1" 8-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.
MicroSD cards offer an inexpensive, flexible and reliable way to bring data logging and data storage solutions to your electronic design projects.
VIN: Input power to the SD card (3.3V to 6.0V)
