A serial SD card module is a device that allows you to read and write to an SD card using a serial communication interface, such as a UART (Universal Asynchronous Receiver/Transmitter) or I2C bus. It typically includes a socket for inserting an SD card and a set of pins or connectors for communicating with the microcontroller or other control device. The module may also include additional components, such as a voltage regulator and level shifting circuitry, to ensure compatibility with a wide range of microcontrollers and devices. Serial SD card modules are often used in projects that require the storage or retrieval of large amounts of data, such as data logging, audio or video recording, or image processing applications.

• SD Card module can make your SD application more easier and simple.
• It is easily interfaced as a peripheral for arduino sensor shield module.
• Through programming, you can read and write to the SD card using for arduino.
• Can be used for SD Card more eaisly, such as for MP3 Player, MCU/ARM system control.
• All SD SPI pins output, MOSI, SCK, MISO and CS.
• Support 5V/3.3V input.
• Size:5.1cm x 3.1cm - 2.01inch x 1.22inch.
