Product Idea: USB Flash Drives

As long as the quad SPI works (which I'm sure it does), we will be able to find some solution. QSPI is quite common for anything that wants to talk SPI (comparitively) fast. I know for example in the automotive industry they rely on this quite bit.

No idea, I think dedicating half hour or so a day to keep an eye on the forum would be manageable.

One thing I was hoping is that we could get a forum section or something, perhaps under "Community Projects" or "Unofficial" or "Prototypes". I did have a quick look last night as well at the possibility of hosting some basic forum too - but I really hate setting up PHP.

How many is a small batch? Also there are pick and place services for common parts, such as those offered by JLPCB. We'd likely need some way to take pre-orders though to judge quantity, and then there's the shipping... And depending on how many you are speaking about creating in a small batch, it could be quite a work-intensive undertaking.

We'd probably need pick and place down the line anyway, as those larger flash chips are quite fine pitch and even quite often have pads/balls underneath that require some oven process.
