Micro Mini SD Card Module

To store your data, media, and other files, simply add the desired memory to your project. This Micro Mini SD Card Module, also known as a Micro SD Adaptor, is suitable for dual I/O voltages. It offers a straightforward way to transfer data from a standard SD card. Additionally, its pinout is compatible not only with Arduino but also with various other microcontroller development boards.

The Micro Mini SD Card Module features an SPI interface that is universally compatible with any sd card, and it utilizes a 3.3V power supply that is also suitable for Arduino UNO/Mega. This versatile module has multiple uses, including data logging, audio, video, and graphics.

In total, there are six pins: GND for grounding, VCC to provide power, and MISO, MOSI, SCK for the SPI bus. The remaining pin, CS, serves as a chip select signal. Additionally, there is a 3.3V regulator circuit that uses an LDO regulator to output 3.3V for the level converter chip and Micro SD card supply.

Micro Mini SD Card Module allows AVR microcontroller systems to interpret the signal.

Included in the package are a variety of features that are sure to enhance your experience.
