DescriptionThe Waveshare ESP32-S3 4inch Display Development Board is a compact HMI board built around ESP32-S3, a 4inch IPS LCD, and 480x480 resolution. It is made for smart control panels, home gateways, industrial control interfaces, lighting control, and LVGL GUI prototypes.The board integrates 16MB Flash, 8MB PSRAM, 2.4GHz Wi-Fi, Bluetooth 5 LE, USB Type-C, TF card, CAN, RS485, I2C, RTC, buzzer, and battery charge/discharge support. The touch variant adds capacitive 5-point touch through I2C.This product has two variants: ESP32-S3-Touch-LCD-4 with touch function and ESP32-S3-LCD-4 without touch function. For an ESP32-P4-based alternative with stronger multimedia focus, the ESP32-P4 development board is a relevant same-brand option.Features ESP32-S3N16R8 with Xtensa 32-bit LX7 dual-core processor up to 240MHz. Onboard 4inch IPS LCD with 480x480 resolution and 65K color. Optional capacitive 5-point touch on the touch variant. 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 LE with onboard antenna. 16MB Flash and 8MB PSRAM for LVGL, HMI graphics, and UI prototyping. CAN, RS485, I2C, TF card, USB Type-C, RTC, buzzer, and battery connector. 7-36V DC input through XL1509-ADJE1 power chip according to the official component list. Two wiring methods with 3.5mm 10P terminal blocks: back wiring or bottom wiring.
