Install

  1. Use a USB cable that carries data (not charge-only).
  2. Plug in a Seeed XIAO ESP32-C3.
  3. Click the button below and pick the serial port.
Stuck? Bootloader mode Hold BOOT, tap RST, release BOOT, then try the button again.

The progress dialog uses a generic time estimate; on this board, flashing is usually well under a minute.

Start fresh (optional)

If the installer asks whether to erase memory first, say yes if you want Wi‑Fi and saved settings cleared—the same as Advanced → Reset all settings in the device portal.

When it’s done

  1. On your phone or computer, connect to the Azimuth-Setup Wi‑Fi network. It appears in your Wi‑Fi list after a first-time flash when you power the board on (before home Wi‑Fi is set up).
  2. A setup page should open, or go to 192.168.4.1 in a browser. Enter your home Wi‑Fi name and password, scroll to the bottom, and save so the board can join your network.
  3. On the PC where you run OpenTrack (same home Wi‑Fi), open azimuth.local:8080. Turn UDP to PC on, click Fill address, scroll to the bottom and save. Then open OpenTrack and pick UDP as the input. More help: quick start.

If azimuth.local doesn’t open, use the device’s IP from your router instead, still with :8080 at the end.
