You can pick up hardware to run Krux for under $50, so it's cheap to try. I like using it on a Maix Amigo because of the large touchscreen, but the M5StickV is another option that is similar in size to a Blockstream Jade.
I can confirm everything works very good with M5StickV, and this is great to have if you like to have smaller size hardware wallet.
Another good thing about M5StickV is that you can run remove Krux code and add some other firmware on it, for example code for Jade wallet can be added following instructions below:

When I purchased M5StickV price was much lower with some discount.
