The Netduino 3 family of development boards has recently been released. I note from the Netduino 3 hardware specifications page that, under "Storage" (Micro SD Cards) the limitation continues to be
"up to 2 GB"
(i.e. it is the same as for Netduino Plus 2).
This is a bit of a problem for me as I'm finding it more & more difficult to find Micro SD cards at this size given the progression of technology. I'm finding that you can still get these low capacity cards but there is a price inversion and they are becoming more costly than 4 GB cards, given that scarcity has come into the equation.
I have seen a few other postings in the Netduino forums that at least mention this problem:
In one of your responses (March 2013) you talked about the potential for upgrading capacity to > 2 GB in a future release.
I'd like to ask where things are with this?
My understanding is that there are (currently) 3 different SD family standards:
- (Original) SD Standard: up to 2 GB using FAT12 & FAT16 filesystems
- SDHC Standard: > 2 GB - 32 GB using FAT32 filesystem
- SDXC Standard: > 32 GB - 2 TB using exFAT filesystem
So I guess what I'm really asking is "What is the potential for Netduino to support SDHC in the near future?" Is this a hardware limitation or (I'm hoping) is it just Netduino firmware &/or the current NETMF implementation?
By the way - for my intended use (the irony of the situation), my data storage requirements are actually far less than any of the capacities mentioned.
