Difference: MicroSdBlocks (90 vs. 91)

STM32F743 Nucleo

There is no serial NOR flash on board, but there is an QSPI interface on connector CN10.

It is easy to connect a MIKROE-4067 with a W25Q128JV (128M-bit) NOR flash memory on it. See also W25Q128JVPIQ.

There are 4,096 erasable 4 KiB sectors. That means 16 MiB are available for the volume.

SDIO Interface is well supported by the STM32H74x, there is no need to use the slower SPI.
