- Desktop Chrome or Edge (Windows, macOS, Linux or ChromeOS). Firefox, Safari and phones don't have Web Serial.
- A USB-C data cable, not a charge-only one.
- Your settings are kept. The installers write only the bootloader, partition table and app, and leave the settings area alone (on the Dial, pairing too) unless you choose to erase.
