BitBox02

The official BitBox comparison separates BitBox02 from BitBox02 Nova. It lists USB communication and Android support for the original device, while Nova adds iPhone/iPad support using Bluetooth. Both have Multi and Bitcoin-only editions. Do not transfer a Nova feature into an original BitBox02 shopping comparison.

BitBox describes microSD backup and recovery, with an option to write down recovery words, and open-source firmware. These statements come from the manufacturer.

A backup that feels quick to create still needs a storage plan. Treat a backup card as a security-sensitive object, not an ordinary spare storage card. Decide how you will label it without revealing secrets and how you will prevent it from being reformatted or mixed with everyday files.

Think through the loss of the whole kit. A device and its only backup in one travel bag have different labels but one failure point. A second location may help with fire or loss, while adding another place that needs access control.

Choose the edition before checking the app. A Bitcoin-only edition is a deliberate limitation, not a switch you should assume can be changed later. For a Multi device, look up the precise chain and token, then the app needed to manage it. Broad phrases such as “multi-asset” should never substitute for this check.

For a shared household computer, consider who can install software and how you will keep the operating system maintained. The dedicated signer does not remove the need to verify the receiving address and transaction displayed to you.

• Are you looking at BitBox02 or BitBox02 Nova?
• Is the exact edition compatible with your intended assets?
• Where will the microSD backup live independently of the device?
• Do you understand the alternative recovery route if that card is lost?

We have not performed recovery drills or physical testing on a BitBox device. Confirm the touch interface and current platform requirements in the manufacturer’s guide.
