Supported hardware: Waveshare ESP32-S3 3.5-inch LCD Touch Display boards. Both the original ST7796/FT6336 and newer AXS15231B display variants are detected automatically.

  1. Plug in the keypad with a USB data cable.
  2. Click Install below and pick the matching serial port when prompted.
  3. Wait for the flash to finish — don't unplug or close the tab.
  4. Connect it to Wi-Fi using the keypad's setup access point after it reboots.
Your browser can't do this. Open this page in Chrome or Edge on a desktop computer — Web Serial isn't available in Firefox, Safari, or on iOS. This page needs to be served over HTTPS to flash devices — reload it from the GitHub Pages URL rather than a local file. Needs Web Serial — Chrome or Edge, desktop only.
