Flash PitScan

Installs the latest release straight from your browser over USB — no toolchain, no command line.

Your browser can't do this — open this page in Chrome or Edge on desktop instead. This page needs to be served over HTTPS to flash over USB.

Before you start

Use Chrome or Edge on desktop — WebSerial isn't available on mobile or in Firefox/Safari.
Connect the board's USB port directly to your computer (not through a hub, if you can avoid it).
This replaces whatever firmware is currently on the board.

Flashing not working? The browser flasher needs the firmware repo's release assets to be reachable cross-origin from this site. If it fails to fetch the manifest or binaries, see the pitscan repo and flash manually with idf.py flash or pio run -t upload instead — see the docs.
