TF Micro SD Card Module Mini SD Card Module Memory Module for Arduino ARM AVR

About this deal

This compact breakout module lets Arduino, AVR, and ARM microcontroller projects read and write data to micro SD and micro SDHC cards (up to 32 GB) via a standard SPI interface. It includes an onboard 3.3V voltage regulator and level shifters, making it safe to connect directly to both 5V and 3.3V microcontrollers. The six-pin control interface (GND, VCC, MISO, MOSI, SCK, CS) maps straightforwardly to any hardware SPI bus. The module communicates over the standard SPI bus and works with the built-in Arduino SD library, so no extra libraries are needed. It supports both reading and writing, making it useful for data logging, audio playback, configuration files, and other applications where onboard flash is limited. The SD card should be formatted as FAT16 or FAT32 before use. A practical, low-cost addition to any hobbyist or prototyping build.
