QSPI-NOR stand for jetson-nano-emmc?

Jetson-nano-emmc (jetson-nano-module not included devkit) knows that SD card is not included.

Can you explain in detail about #1 and #2?

Thank you.

Hi,

No, that has nothing to do with emmc module. You could google search what is qspi flash first.

For nano-sd (devkit) module, there are two components to make your device work. One is QSPI-NOR and the other one is the sdcard.

However, for nano production module (emmc), there is no sdcard but replaced with emmc.
