Firmware installer — ESP32-S3-Touch-AMOLED-1.75 and ESP32-P4-WIFI6-Touch-LCD-4C
Flash the firmware straight from your browser — no toolchain, no PlatformIO.
Use Chrome or Edge on desktop (Web Serial required).Serve this page over HTTPS to flash.
Installs firmware v1.19.5
Plug the board into your computer with a USB-C data cable. Either board works — the installer detects which chip you have and picks the matching build.
Click Install and pick the USB JTAG/serial (or USB Serial) port.
Choose Erase device + Install for first-time setup.
When it reboots, join the board’s setup WiFi from your phone to enter your network and home location — SkyGlass-S3-Setup or SkyGlass-P4-Setup depending on which one you flashed.
Fine-tune anything later at http://skyglass-s3.local/ or http://skyglass-p4.local/ — each board answers to its own name, so you can run both at once.

Leave Erase device unticked to preserve your WiFi credentials, settings, and uploaded alert sound. Ticking "Erase device" will wipe them.
Updating over WiFi at http://skyglass-s3.local/update or http://skyglass-p4.local/update also preserves everything and needs no cable.
