OpenWrt One / project update

[Fernando Frediani]

Hi Felix
Thanks for the clarification.

Yeah, USB may be Ok, but M.2 isn't for all usages, specially the 
simplest and less costly ones. I see that a SD Card is still quiet 
universal, very cheap for all sorts of projects.
Regarding the the standard for the SD card spec I can't answer that, but 
I would say that whoever uses it should not expect high performance, but 
rather simplicity and cost. Those who may need storage performance may 
well use the M.2.

I see a Winbond 25N01GVZEIG NAND memory in the PCB which seem to be 
128MB of storage. Can I understand that can be used similarly to a SD 
Card for projects which don't require much storage space ?

Thanks
Fernando

Should the micro SD card slot use UHS-III or SD express? both at the same time isn't possible even though the cards look the same). The SD card spec can't keep up with CFexpress in the camera sector.
