Guition 4" ESP32-S3 Touch Display Module
480×480 with 3 relays (ESP32-4848S040C_I_Y_3)
The Guition ESP32-4848S040C_I_Y_3 is a compact 4-inch square IPS touch display with an ESP32-S3 microcontroller built in. It's a great fit for smart home wall panels, thermostats, control screens and other small HMI projects. The dual-core ESP32-S3R8 drives a crisp 480×480 screen and has 2.4GHz Wi-Fi and Bluetooth LE built in. A demo program comes pre-loaded, so you can power it up and start testing straight away.
This is the three-relay version (ESP32-4848S040C_I_Y_3): a relay module on the back of the panel gives you three relay outputs that you can switch from your own code, ESPHome or Home Assistant, so the screen can work as a smart wall switch as well as a touch control panel. Check the relay rating printed on the board before wiring anything up, and have mains wiring done by a qualified electrician.
