Button grid

The home screen uses a 3-row × 3-column grid, giving you 9 button slots. Any button can be turned into a subpage folder containing up to 8 more buttons.

Double-height buttons are supported — any button can span two rows for easier tapping.

Install

Connect the display to your computer with a USB-C data cable, then click the button below.

Your browser does not support WebSerial. Use Chrome or Edge on desktop.

For a full walkthrough including WiFi setup and Home Assistant pairing, see the Install guide.

After flashing or OTA update

This panel uses MIPI RGB with octal PSRAM, which requires a brief hardware reset after flashing or OTA updates. The firmware handles this automatically with a short deep-sleep cycle — the display may flicker once before coming back up normally.
