The X-NUCLEO-SPINAND-MAC board is the Macronix MX35LF1GE4AB-Z4I 1Gb SPI NAND Flash evaluation board (shield) for STM32 Nucleo boards. It is compatible with the Arduino UNO R3 connector layout. The X-NUCLEO-SPINAND-MAC interfaces the memory with the STM32 MCU via SPI pin, and the user can change the default SPI clock.
