In Lime 2 what is the difference between model e16Gs16M and n8G?
e16Gs16M has 16GB eMMC flash memory and 16MB SPI memory
n8G - has 8GB NAND memory
If you are looking to use latest Olimage Linux images, it is recommended to get the eMMC flash memory version. NAND memory is not supported in the recent kernels and you will be stuck with older kernel images.
