It typically uses the SPI interface to communicate with the microcontroller. An SD card reader module is a small circuit board that connects to an Arduino or similar microcontroller. It provides a way to store and retrieve data from an SD card, which is a common storage medium in embedded systems. The module usually includes a socket for the SD card and a set of pins that connect to the microcontroller via the SPI (Serial Peripheral Interface) protocol. <dl> <dt style="font-weight:bold;"> <strong> SD Card </strong> </dt> <dd> A small, removable storage device used in digital cameras, smartphones, and microcontrollers to store data. </dd> <dt style="font-weight:bold;"> <strong> SPI Interface </strong> </dt> <dd> A communication protocol used for short-distance, high-speed data transfer between microcontrollers and peripheral devices. </dd> <dt style="font-weight:bold;"> <strong> Microcontroller </strong> </dt> <dd> A small computer on a single integrated circuit, often used in embedded systems for automation and control. </dd> </dl> The Micro SD Module TF Micro SD Storage Board TF Card Memory Shield SPI Interface Compatible for Arduino is a typical example of an SD card reader module.
