JadeLink is a USB-C storage drive designed for pairing with Jade Plus to perform air-gapped firmware upgrades and transaction signing. When using JadeLink in combination with the Jade Plus camera, you can perform all functionality possible with a Jade Plus in a completely air-gapped manner (including device unlock and receive address verification).
Note: You can use most generic USB drives and SD cards formatted to FAT32 for this functionality. JadeLink is not specifically required.
