  1. Plug the XIAO ESP32-S3 into this computer with a USB-C data cable.
  2. Click Install below.
  3. Pick the serial port that appears, then wait ~30 seconds.
Your browser can't flash over USB. Please use Chrome or Edge on a desktop computer (Web Serial isn't available in Firefox, Safari, or on mobile).

If flashing fails or no port shows up: hold the BOOT button, tap RESET, release BOOT, then click Install again. After a successful flash, unplug and replug the board once — it should appear over Bluetooth as Octopus-16-XXXX.
