Custom MicroSD Card Adapter module SPI interface TF card reader with level conversion chip

This module (MicroSD Card Adapter) is a Micro SD card reading and writing module. Through the file system and SPI interface driver, the microcontroller system can read and write files in the MicroSD card. The SD card library that comes with the IDE can complete the initialization and reading and writing of the card

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
