Micro SD Card Module Mini TF Read and Write SPI Interface Power Supply with Level Conversion 10PCS _x000D_ Micro SD card module/Mini TF card read/write/SPI interface/Power supply with level conversion _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ Baby description: _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ This module (MicroSD Card Adapter) is a Micro SD card reading and writing module. Through the file system and SPI interface driver program, the microcontroller system can complete the reading and writing of files inside the MicroSD card. Arduino users can directly use the SD card program library provided with the Arduino IDE to complete card initialization, reading, and writing _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ The module features are as follows: _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ 1.
