This module is a Micro SD card read-write module, which allows the microcontroller system to read and write files from the Micro SD card through the file system and SPI interface driver program. Arduino users can directly use the built-in SD card library in Arduino IDE to initialize and read/write Micro SD cards through this module.
The Micro SD card module cannot be used as a flash memory to write functions, and can only make read and write calls to files inside the SD card.

Product Overview:
This module (MicroSD Card Adapter) is a Micro SD card read-write module that allows the microcontroller system to read and write files from the MicroSD card through the file system and SPI interface driver program. Users can directly use the built-in SD card library in Arduino IDE to complete card initialization and read/write operations.
Module features:
1. Supports Micro SD card and Micro SDHC card (high-speed card)
2. On board level conversion circuit, i.e. interface level can be 5V or 3.3V
3. The power supply is 4.5V~5.5V, with an onboard 3.3V voltage regulator circuit
4. The communication interface is a standard SPI interface
