Thanks, feels good to not be alone. I see this kind of hardware and just shrug. But I'd really love to be the kind of person who sees the possibilities and says "wow this is super nice!" (-:

Black hat shenanigans, maybe.

2FA token is the most obvious use case I can imagine. Otherwise you can do some programming practice. You are limited on IO though.

I've been wanting to learn FPGA to build hardware accelerated compression for external storage[1], Would these HW be a good start?

It's an excellent educational device to introduce people to embedded development.
