I just noticed that with the latest firmware version you released a few months ago, a new device has become compatible with the Krux DIY hardware wallet. It's the Yahboom K210 module. It's a touchscreen device that runs on Linux and has a touchscreen. It's cheap and can be bought for $50 to $60 at Amazon.

Next release the Cube will have official support as well, currently it's only supported through the beta release.
