Web USB flasher
Flash a device
Install firmware straight from the browser over USB. Nothing to download and nothing to install — plug the board in and go.

Needs the board plugged inRun the steps in order the first time. Installing is a one-off — after that the device takes its updates over the air — and the rest are here whenever you want to change the Wi-Fi, the clock or the location.
Setting up over USB needs Chrome, Edge, Opera or Firefox 151 or
later. Safari cannot do it.
