BitBox02 or BitBox02 Nova?

Nova works with BitBoxApp on iPhone over Bluetooth, while the phone or another suitable source supplies power through the physical connection. The original BitBox02 has no iPhone signing workflow: an iPhone’s USB-C socket does not change that.

On Android, both models use USB and require USB OTG, which lets the phone communicate with an external device. Nova’s Bluetooth support is for iPhone and iPad, not Android.

Both connect by USB, show transaction details on an OLED display and use touch-sensitive edges. Nova adds a glass-covered display; it does not turn the device into a touchscreen. You still review the address and amount on the wallet.

If your original BitBox02 works with your computer and you can comfortably read and operate it, USB use alone gives you no reason to replace it. Nova is a more concrete upgrade when you need iPhone signing or prefer its glass-covered screen.

What to check before approving a payment 

Both generations have fixed Multi and Bitcoin-only editions. Choose the device for your phone or computer, then the edition for your assets. A Multi edition cannot later become a Bitcoin-only device, or the reverse.

An existing BitBox backup can restore the same wallet on a compatible replacement. Preserve the microSD backup or recovery words and any exact optional passphrase; the new edition and app must also support the accounts you need. If you instead create a new wallet, transfer to its new addresses before retiring the old setup.
