Flash lynx from your browser.

One click puts the lynx firmware on a Seeed XIAO ESP32-S3 Sense: servos, camera, and a control layer you reach over your network by HTTP or MCP.

Plug the XIAO into this computer with a USB-C cable that carries data. A bare board, or the assembled lynx through its base port.
Click Install and pick the port named USB JTAG/serial or ESP32-S3. Choose Erase on a first install.
Join the lynx-xxxx Wi-Fi hotspot from your phone when flashing finishes. The setup page opens by itself: pick your network and save the device token it shows you.

This browser can't reach USB devices. Use Chrome or Edge on a desktop. USB access needs a secure page (https).

No port in the list? Hold the board's BOOT button while plugging it in, then try again.
