Product Description：
This module (MicroSD Card Adapter) is a Micro SD card read and write module. Through the file system and SPI interface driver, the microcontroller system can read and write files in the MicroSD card. Arduino users can directly use the SD card library that comes with Arduino IDE to complete the initialization and reading and writing of the card
The module features are as follows:
1. Support Micro SD card, Micro SDHC card (high speed card)
2. Onboard level conversion circuit, that is, the interface level can be 5V or 3.3V
3. The power supply is 4.5V~5.5V, and the onboard 3.3V voltage regulator circuit
4. The communication interface is a standard SPI interface
5.4 M2 screw positioning holes for easy installation
