VKLSVAN 6PCS Micro SD Card Module Mini TF Card Adapter with Memory Storage Breakout Board SPI Interface Driver TF Card Adapter

["The module is a Micro SD card reader module, and the SPI interface via the file system driver, microcontroller system to complete the MicroSD card read and write files.","On-board level shifting circuit, interface level can be 3.3V or 5V. Power supply is 5V, onboard 3.3V regulator circuit. Communication interface is standard SPI interface.Micro SD card into the direction of signals into 3.3V, MicroSD card toward the direction of the control interface MISO signal is also converted to 3.3V, general AVR microcontroller system can read the signal.","Through the file system and SPI interface driver, the MCU system can completethe reading and writing of files in the MicroSD card.Users can directly use the IDE comes with an SD card to complete the library card initialization and read-write.","Support Micro SD card(≤ 2G), Micro SDHC card (high speed card ≤ 32G).","3.3V regulator circuit: LDO regulator output 3.3V as level converter chip, Micro SD card supply."]
