# Title: microSD Click Board™ ## Description: Need more additional memory? We've got just the thing for you - microSD Click Board™. It features a microSD card slot for microSD cards used as a mass storage media for portable devices. microSD click is designed to run on 3.3V power supply. Industry standard SPI interface ensures simple communication at high data rates. Use it for reading or storing data like music, text files, videos and more. USING MICROSD CARDS Board contains the slot for standard microSD cards. Once power is turned on, power LED will indicate that board is in operation. Data is read and written to the card using industry standard SPI interface. POWER SUPPLY – 3.3V ONLY Board is designed to use 3.3V power supply only. If you need to add MMC/SD feature to your 5V prototype or development board, we recommend you to use other boards such as the MMC/SD Accessory Board. SPECIFICATIONS Type microSD Applications The microSD Click Board™ is ideal for storing and reading acquisition data, images, music, video and data files, or any other application where fast mass storage is needed.
