Product Idea: USB Flash Drives

[barray]

Thanks for typing that up @dsimic - and to others I recommend popping into IRC to chat It's a little bit quicker to throw some ideas forwards and backwards, then write them up here.

I think the Cortex-M7 is maybe even slightly too powerful - but that offers exciting future possibilities too. I also believe the Cortex-M7 will be continued to be produced for quite some time as yet, so we should be safe from EOL.

The Teensy 4.1 board does look like a good development platform. The only real thing to add is a QSPI flash chip or 2 for data storage. If the code size exceeds the 8MB built in program flash, it does appear you can use another, separate SPI.

Of course, during development the Micro SD card comes in quite handy.

I think we would be initially looking to just use the micro-SD for storage as we prove out the USB firmware, then look to expand the storage. Probably as a Teensy hat or something - then we can look to build a proper board.

Support for FIDO2 authentication would be cool to add, similar to this: https://github.com/solokeys/solo

For sure in future versions we would be very much interested in such things. Creating an open source flash platform also allows for other people to experiment with such things
