A MicroSD card is a miniaturized flash memory card used for data storage in compact electronic devices like smartphones, tablets, and drones. It consists of a NAND flash memory chip for storing data, a controller chip for managing data transfer, and a printed circuit board that connects them. To connect to computers, a MicroSD adapter or a USB card reader is used to fit the small card into larger SD slots or USB ports.
