This flash memory module allows you to store and read data externally via the SPI interface of your microcontroller. The module is controlled exactly like a conventional SD card and is therefore particularly simple. The module can be operated with 3.3 V as well as 5 V thanks to the integrated voltage converter. Specifications - Operating voltage: 3 ... 5 V - logic level: VCC - Interface: SPI - memory size: 512 MB - clock frequency: up to 50 MHz https://elecena.pl/product/21954090/com-sd-nand512-developer-boards-512-mb-sd-nand-flash-memory 2022-10-31 https://elecena.pl/product/21954090/com-sd-nand512-developer-boards-512-mb-sd-nand-flash-memory 2023-05-01 https://elecena.pl/product/21954090/com-sd-nand512-developer-boards-512-mb-sd-nand-flash-memory 2024-03-10 https://elecena.pl/product/21954090/com-sd-nand512-developer-boards-512-mb-sd-nand-flash-memory 2024-07-02
