This week I finally had free time and I finally managed to flash one of my M5StickV device that was collecting dust, and I installed Krux firmware.
Whole procedure is very simple and it takes only few minutes to complete after downloading latest firmware 22.08.1 from Krux github page.
Nice thing is that you can do this easily on most operating systems like Linux, Mac and wiNd0ws, following instructions from Getting Started page:
https://selfcustody.github.io/krux/getting-started/ Turning on device for the first time shows you menu screen, so you can than Load Mnemonic or create new one using D6 (standard six-sided die) or D20 dices (20-sided die).
Loading Mnemonic can be done via QR codes (easiest option), or importing Text, Numbers and Bips using BIP-39 standard.
Note that importing seed words manually is time consuming, so I suggest generating seed words offline in any method you like and importing it with QR code.
Ian Coleman's BIP-39 Tool is able to generate mnemonic with QR code you can import to Krux, but you need to select 12 or 24 words.
After this you can Add Passphrase if you want, and choose between Single-key and multisig.
Device has miniature battery so it can work without any cable connection, it has camera with light, but there is no way to see how much battery is charged and I don't like that.
It's easy to open device with unscrewing two screws and you can see everything inside, replace battery, camera or any other part.
Navigation is not that great and it's done with two plastic buttons on both sides of device with main confirmation button that is on front side below screen.
To put things into perspective I have to say that device dimensions are very small: 48*24*22mm.
I will test how everything works, pair it with different wallets and post updates in future.
