Micro SD Storage Expansion Board Micro SD TF Card Memory Shield Module SPI For Arduino Promotion

Descripción

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.
