Intelligent SD card reader/writer

The PC-SDRW-02 is an intelligent SD card reader/writer equipped with a FAT file system. It adopts a serial interface (TTL UART/SPI) for the host interface, making it easy to connect to microcontrollers. Files can be manipulated with simple commands, allowing for easy addition of storage functionality to embedded systems. When connecting to our Alpha Board series, it can be used simply by connecting to the serial interface connector of each board.
